Audi S4 B8 Brake Upgrades

Stage 1

Brake upgrade consists of  EBC Yellow stuff pads

Although a full race material and capable of high temperature use with very good wear life, this new formulation sets a new trend in race type brake pad compounds. The “bite” from cold is superb which is uncommon with race materials (normally requiring warm-up) and makes this a pad which can be safely used on the road as well as on the race track. This new formulation was used by numerous championship race and rally drivers in 2004 and is truly a milestone in brake pad material development.

 High efficiency performance and race brakes for track & street use, fast to bed-in, great for street vehicle brake upgrade.

Not only a high friction pad but very resistant to heat and loads of heavy braking means that yellowstuff has been used with great success in race cars and on high speed Police Vehicle brakes alike.

EBC Yellowstuff pads are used on the UK Silverstone Race Track Drivers experience cars because of their high performance and longevity. Yellowstuff also claimed a win in the Targa rally and for two years running in the Brazil Mitsubishi off Road Team Desert Challenge

Because of its huge heat range , the applications where EBC Yellowstuff will deliver benefits range from fastest street use on higher horsepower cars to Trackday and Race use on most street based cars.

Stage 2

The B7 RS4 brake upgrade removes the original caliper and replaces it with the components found on the B7 RS4, the 8-piston caliper along with the two-piece bell and disk.  Wheel spacers may be required in some cases. Pagid RS4-2 Blue pads are recommended with this upgrade.

 Brake fluid upgrade


ATE Super Blue Affordable high performance brake fluids that have both a high dry boiling point (280 deg C) and a high wet boiling point (198 deg C), but without being excessively hygroscopic. What this really means is that these fluids do not readily absorb moisture like most high performance fluids. Moisture in your braking system can be costly requiring a complete braking system overhaul! A must for any car equipped with modern high friction brake pads.

If you're thinking of replacing your brake lines, pads or just want to get better performance out of your stock brake system, this is a great product to make bleeding your brakes worth your time. Don't replace your brake fluid with stock fluid if you have the opportunity to go to a performance brake fluid like the ATE Fluid.
