Located at the end of these installation instructions is a How-To Guide for Brake Pad Replacement

Provided brake pads are for spirited street use. For track use, different pads are required. See step 28 for recommendations

OE wheels will require the use of a wheel spacers for proper clearance and operation

Some aftermarket wheels will require the use of a wheel spacer for proper clearance and operation

Use this Wheel Fitment Guide link to check the BBK clearance for your wheels: https://store.27won.com/_27Won/27Won-1-P...

These instructions reference the separate sides of the vehicle as "Left Hand" & "Right Hand". Left Hand & Right Hand is always defined from the driver seat viewpoint

Brake fluid is corrosive to paint. Do not let brake fluid sit on painted surfaces for extended periods of time

Raise the vehicle and support with jackstands in the OE recommended locations and remove the front wheels/tires

The following instructions show the left-hand side complete removal of OE components and installation of 27WON BBK. The right-hand side is completed with the same steps

Brake Rotor, see red arrow

Brake Caliper, see orange box

Brakeline attachment point to Chassis, as shown with yellow circle

Use a 12mm socket and ratchet to remove the bolt shown with red circle

Use a 17mm socket and breaker bar to remove the two caliper bolts

With the bolts removed, slide the brake caliper off the rotor in the direction of the orange arrow

If the rotor is heavily worn, you may need to spread the brake pads apart to gain clearance

Hang the caliper off to the side as shown using a bungee chord

Failure to suspend the caliper with the brake line connected could put stress on the lines and cause damage

Use a #3 Phillps screwdriver to remove the rotor retention screw

You may need to let this soak with a small amount of WD-40 or equivalent spray

With retention screw removed, slide the rotor outward off the wheel studs

Caliper Brackets

Mounting holes to vehicle

Mounting holes to BBK Caliper

Short Socket Cap Bolts

Apply small amount of blue Loc-tite to threads as shown on two of the short socket cap bolts

Install provided caliper bracket as shown

The flat face of the bracket should be facing out for proper rotor clearance

Hand thread the short socket cap bolts

Using the 10mm hex bit socket and torque wrench, torque to 64-71 ft-lbs

The 27WON BBK has directional brake rotors - therefore it is critical that the correct rotor is installed on the correct side of the vehicle

The direction of the angled slots allows you to identify if the rotor is LH or RH

Left Hand Rotor (LH) - This rotor will go on the Left Hand side of the vehicle

For North American cars this is the driver side

Right Hand Rotor (RH) - This rotor will go on the Right Hand side of the vehicle

Rotors come with machine oil on them to resist corrosion - clean both rotors with brake cleaner spray and clean rag

Left Hand side of vehicle shown - locate the Left Hand rotor for install

Install the rotor over the wheel studs

Align one of the chamfer holes in the brake rotor with the rotor retention screw hole.

Install the OE #3 Phillips rotor retention screw removed in an earlier step. Tighten with screwdriver

At this point you may notice some contact between the rotor and the dust shield behind it. This is not damaging the rotor. See next step

Check the clearance between the rotor and the dust shield

Inspect clearance around the entire circumference of the rotor

If there is less that 1/4" clearance, push the dust shield away from the rotor to get the clearance

27WON BBK has directional brake calipers - therefore it is critical that the correct caliper is installed on the correct side of the vehicle

Left Hand Caliper - This caliper will go on the Left Hand side of the vehicle

For North American cars this is the driver side

Right Hand Caliper - This caliper will go on the Right Hand side of the vehicle

Long Socket Cap Bolts

Included with the hardware is a pack of very thin washers. These are used as spacers for the rare case that the position of the caliper needs to be adjusted

Rotor installation may have put dirt/grease on rotor faces - clean rotor with brake clean spray and clean rag

Locate the Left Hand Caliper - Left Hand Caliper Shown

Mounting Holes, oriented as shown

Top of Caliper - Bleed Screws on Top, oriented as shown

Apply small amount of blue Loc-tite to threads as shown on two of the long socket cap bolts

Install the caliper over the rotor - the rotor will go between the brake pads as shown

Hand thread the long socket cap bolts

Using the 10mm hex bit socket and torque wrench, torque to 64-71 ft-lbs

Locate the provided stainless steel braided brakelines

Caliper side of brakeline w/blue dust cover

Chassis side of brakeline w/blue dust cover

Rubber Strut Mount Isolators

Locate the provided Banjo Bolts

Locate the provided 10mm Crush Washers

Once components are inspected, remove the blue caps off the 27WON brake lines

Remove the blue plastic dust cover and assemble the hardware as shown

Banjo Bolt

Crush Washer

Brakeline - Notice the angle of the brakeline, verify the head of the banjo bolt is on this side as shown

Installation of brakeline to caliper on opposite angle may cause a crush washer leak

Crush Washer

Install the brakeline onto the caliper as shown - hand tighten the banjo bolt with the brakeline routed upward

Using a 14mm socket and torque wrench - torque to 8-12 ft-lbs

Route the brakeline as shown

Slide the rubber strut mount isolator along the brakeline then press the isolator into the strut bracket as shown

Verify that the brakeline is not contacting any part of the vehicle - adjust the brakeline routing if contact is found

Locate the chassis side brakeline connection

The next step will disconnect the brakeline. This will allow brake fluid to leak from the hard brakeline mounted to the chassis and the rubber brakeline on the caliper. Use a rag to catch drips

It is critical to use a Line Wrench to loosen the brakeline connection. Using the open end of a standard wrench may round over the corners

Use a 10mm line wrench to loosen the threaded brakeline connection (shown with orange box) then pull chassis side brakeline from the connection

Use a large flat head screwdriver to pry the retention tab out as shown with the arrow

Pull the retention tab outward in the direction of the arrows

Pull the OE rubber brakeline down and out of the mounting bracket

Use a 12mm socket & ratchet to remove the bolt

With the brake line disconnected, remove the OE brake line and OE caliper

Remove the large 19mm nut from the brake line

Route the brake line through the chassis mounting bracket in the direction indicated by yellow arrow

Re-install the large 19mm nut onto the brakeline hand tight

Hand thread the hard brakeline fitting into the brakeline

Hold the lower hex with a 17mm wrench, then tighten the upper nut (green arrow) with a 19mm wrench - tighten until very snug

Using the 10mm Line Wrench, tighten the hard brakeline fitting (light blue arrow) until very snug

Re-install the bolt using a 12mm socket and torque wrench - torque to 10-14 ft-lbs

This completes the BBK installation for the left hand side of the vehicle. The right hand installation process is the same

Complete the right hand installation process starting on Step 4

This completes the installation of the BBK physical parts - The following steps provide instruction for Brake Bleeding and Brake Pad Bedding

Located at the end of the installation instructions is a How-To Guide for Brake Pad Changes

Both Left Hand and Right Hand BBK Systems must be installed completely before proceeding to the Brake Bleeding Procedure

Clean all brakeline connections at chassis and caliper with brake clean spray and clean rag

Tools - You will need a fresh container of Dot 4 Brake Fluid, bleeder bottle and hose as shown (the hose should fit tight on the bleeder screw), 10mm box-end wrench, and a friend to help with the process

For best results, always start with the bleed screw located the furthest away from the master cylinder and work your way closer. There are two bleed screws for each caliper. Follow the order below

First Bleed Screw - RH Outside

Second Bleed Screw - RH Inside

Third Bleed Screw - LH Outside

Last Bleed Screw - LH Inside

Remove the cap from the bleed screw as shown

Place the box end of the wrench over the bleed screw hex as shown

Put one end of the hose on the bleed screw as shown

Hang bottle from wheel studs as shown or set on ground

Have yourself or your friend setup in the driver's seat so that they can press the brake pedal firmly

Have the other person setup at the brake caliper so they can open/close the bleed screw

To open/close the bleed screw - you only need to turn the wrench ~1/4 turn

Have the person in the driver's seat press the brake pedal 3-5 times until there is sufficient pedal pressure. Then, have them hold the brake pedal firmly as the bleed screw is loosened. The pedal will go to the floor while fluid and air will enter the bottle. Make sure your friend holds the pedal down as you retighten the bleed screw.

The brake pedal will go to the floor while fluid and air will be pushed through the open bleed screw

Continue holding the brake pedal down until the bleed screw is re-tightened/closed

Repeat the above procedure around 3-5 times per bleed screw, or until your are confident there is no air in the system Check that your brake fluid level is at “full” after each bleed screw.

After each bleed screw is completed, check that your brake fluid level is at “full”. Refill as needed

Move to the next bleed screw as listed in Step 23 until all four bleed screws have been completed

Once brake bleeding is complete, inspect all brakeline connections at chassis and caliper to verify there are no leaks

If the brakes are properly bleed the brake pedal should have distinct "feel" to it

Brake pedal should have minimal down travel before pressure/force is felt

Brake pedal should feel firm after a small amount of down travel - it should not feel "spongy" or loose pressure over a quick amount of time

If your brake pedal does not correlate with the above, then go through the brake bleeding procedure again

Brake pad bedding is an essential process to the life and durability of the brake pads and rotors - for optimal BBK performance please follow the steps below

Proper pad bedding slowly heats and cools the rotors & pads - do not hard brake during initial driving until after complete bedding procedure is complete

Find an open road and accelerate to 30mph - Brake evenly and smoothly at ~50% effort until the vehicle is almost stopped, then accelerate to 30mph again

Repeat above step 8-10 times

Find an open road and accelerate to 50mph - Brake evenly and smoothly at ~80% effort until the vehicle is almost stopped, then accelerate to 50mph again

Repeat above step 2-3 times

Allow ~15min for brakes to cool - You can now use the brakes for normal driving

All braking systems are a compromise of Performance, Dust, and Noise. These factors are all highly dependent on the brake pad material used

The 27WON BBK arrives to your door with a brake pad material we found to be a good compromise of the above three factors. The pad material is considered a "street sport" setup that will provide a low amount of dust, nearly zero noise (some noise if very cold), and good performance for most street driven applications

The 27WON BBK is designed around a very common pad size and shape. If desired you may seek out a brake pad compound that better suits your driving style and application

Brake Pad Options by Manufacturer - There are many more options available than shown

Hawk - HB110

Carbotech - CTCP3215

G-Loc - GPX6

This completes the installation & setup of your 27WON Performance Front Big Brake Kit

Proceed to the next step for the How-To Guide for Brake Pad Replacement

Using a 5mm Allen wrench, remove the caliper bridge bolt

While loosening the bolt, push on the bridge spacer towards the rotor then remove the bolt

Remove bridge spacer and spring clip

Using a flathead screwdriver, push the brake pad away from the rotor as shown to provide clearance

Typically the brake pad backer plate has a small edge that can be pushed against

Locate the 90 degree pick tool for the next step

Using a 90deg pick tool, hook the pick on the backer plate of the brake pad then remove brake pad

Pull the top and bottom of the brake pad in even increments until the pad can be fully removed

With the brake pad removed you can now access the caliper pistons directly - you will need to fully press the pistons into the caliper to provide clearance for new brake pads

Sometimes while pressing one piston in, another piston will push out. If necessary, hold the other pistons in place while pressing a piston into the caliper

Install the new brake pad into the caliper as shown

Verify the brake pad material surface is towards the rotor face and the backer plate is towards the pistons

Repeat Step 30 & 31 for the remaining used brake pad

Re-install the brake pad spring clip and the caliper bridge spacer - hand thread the caliper bridge bolt and torque to 8-10 ft-lbs

Complete the Brake Pad Bedding Procedure in Step 27
