Brake Shudder

[Trough Lolly]

How come some are getting this brake shudder and some are not ?

I had my original brakes on for 15 thou and no shudder. I have had the Brembo 6/4 set up on for twenty thou and never a shudder. Not in light braking, creeping or full on hard braking. I am a left foot braker and drive an auto. I don't get it.

I changed the brake fluid to Penrite Sin when my car had 5,000 kays on it as I boiled the original fluid.

Surely it cant be brake fluid.

the brembo equipped cars dont suffer the brake shudder problem, its mostly the early BA's with std 2 pot setup.

usually a DBA rotor change and some decent pads cured the problem.

caught myslef out the other day.

I did a big stop as some lights on an off ramp went red and I had to pull up fairly hard. After 10 seconds of being stoped I realised I still had my foot hard on the brake pedal - I could see how doing this once would be just enought to fubar a rotor.

I think the major cause of this is pad deposit on the disc.

Firstly the pads have to be bedded in properly, StopTech : Balanced Brake Upgrades

The idea is to deposit a thin even film of pad materiel onto the disc.

If you have an full on stop and leave the brakes applied a lot of pad material is deposited in one spot. (Ive seen cars with the outline of a pad perfecly deposited on the discs.)

This is what causes the shudder, that's not to say everyones comments are not good advice, but I think on the falcons this is the major cause.

I had 90.000 km up with no shudder untill I Had a very hard stop and had to hod the car on brakes as it was on a hill. After this it was shudder City.

The biger brakes should fix it permanantly as they dont get as hot.

DBA Steve I read your email earlier thanks for the assistance...I have recently re skimmed the rotors and I will see how we go... if the problem perists again I will follow you up on your offer...everyones advice make sense an I am fully aware of the heat spot created after a hard stop to a halt scenario so where practicable I try to avoid this situation.

From what I know the Bendix Ultimates/DBA 4000 set up is what was used by the NSW HWY Patrol on their BF range and im quite sure they would have put this setup through its paces but I havent heard any complaints anwhere and with such a large fleet im sure if there was aa problem you would have heard about it.
