Audi TT/Volkswagen Mark IV Front Big Brake Upgrade

These instructions are for the Audi TT and Volkswagen Mark IV chassis vehicles. The photos shown are of an Audi TT. The Volkswagen applications use the same caliper brackets, rotors and hats, and the caliper bodies are identical, so the installations are very similar on all vehicles. The one main difference is the brake lines, which may vary slightly from the photos shown. Also, brake pad wear sensors and ABS line routing may vary. Though the actual fitment may look slightly different, the order in which the kit is installed is the same for all vehicles.

Caliper, Hat and Bracket Finish Disclaimer
Many wheel-cleaning solutions contain strong acids that may damage the finish on any caliper and or aluminum anodized finish, especially the plating on the hardware. Check for adverse effects by trying a small amount of the cleaner in question on an inconspicuous area. Avoid over spraying, and rinse the cleaning solution off as quickly as possible. STOPTECH will not be held liable for damage to caliper, hat or bracket finish due to corrosive chemical exposure.

Step 1
Jack up the car.
Apply Parking Brake and properly block rear wheels.
Remove plastic wheel nut covers using the factory supplied tool.
Brake loose the lug nuts on both front wheels with a 17mm socket (for stock wheels) before jacking up the vehicle and secure on a pair of jack stands. Or jack one side only using a single jack stand of suitable load rating.
Refer to the Owners Manual for correct location for jacking up the vehicle. Jack up the vehicle and secure on a pair of jack stands. Or jack one side only using a single jack stand of suitable load rating.
Step 2
Remove Wheels
After securing the vehicle at a convenient height, remove the front wheels.
Wheel shown may not be representative of vehicle described in this manual.
Step 3
Remove Inner Brake Line Connection
WARNING - Brake line fluid will damage most painted surfaces. Immediately clean spilled brake fluid from any painted surfaces.
Place a drip tray or several rags directly below the inboard brake line connection. If the area around the connection is dirty, clean with brake cleaner or appropriate cleaning agent
Note- Be sure the cap is securely installed on the master cylinder. If the cap is loose or removed, it is likely more fluid will drip.
Using an 11mm wrench, loosen and remove the hard line fitting from the stock brake line.
Removal of Clip Shown
Quickly place one of the rubber caps over the end of the hard line. This should effectively con- trol fluid loss for the duration of the installation.
Note- Brake fluid will drip onto your hands during this operation. Latex gloves may be preferred. Be aware that brake fluid will soak through fabric or leather gloves and transfer to everything touched after that.
