Identifying and Correcting Disc Brake Judder

Braking regularly from 80 mph, this is what you can expect from Riviera brakes in stock form. If you feel it in the steering wheel, it's the fronts. If you feel it while applying the P-brake at speed, it's the rears. Cheap fix: Hawk HP+ pads and a fresh set of rotors. These pads make noise, will dust up your wheels, and do eat rotors over time, but they'll fix the judder issue. Better fix: F-Body calipers with EBC Bluestuff pads and a fresh set of rotors.

Do the front rotors first. The rears may be ok. Easy way to check the rears is to engage the parking brake while car is rolling.

Probably should make sure the car is in neutral while rolling and applying the P brake. Right?

You can apply the P-brake when in any gear, just don't be in a turn when you do it.

Just a note of caution....the last time I applied my parking brake, it got stuck. The cable was corroded. I had to take the cables off of the rear calipers to release them.

AA is right about the P-brake "judder" being rear rotors. But usually, when you have a brake pulse, if the steering wheel isn't shaking, the rear rotors are warped. You will also feel the brake pedal pulsing, and you'll feel it in the seat of your pants. No joke. Maybe I've been doing it a long time (working on cars) and just know, but you can usually tell if it's the fronts or the rears by those "feelings".

I just don't want your P-Brake to get stuck

But that's how I drift! How else am I supposed to drift my turn off an off ramp @ 45-55mph!?

My advice assumes your P-brake gets used regularly and has been tested it at low speed before engaging at high speed. I've found my P-brake to be extremely reliable in use.

If you enjoy launching into the weeds ass-first, this a great plan!

Nah, I just give it a lil love tap, to lock the back wheels up and to get them to slide out from the direction im turning. Then when im in the turn, i lay off the gas and brake and just let her go. As soon as traction is back on, im back on the gas. VRRRROOOOOOM, I LOVE OFF RAMPS + GREEN LIGHTS.

great except you have to remember the push-to-release pedal is a bit prissy at times... I do this in the snow in parking lots sometimes for kicks, but leave it alone on the road.
