Rear Wheels Locking Up

[Black Viper]

I have a problem with my rear wheels locking up first under hard braking. My fronts don't seem to lock up.

It's not due to brake fade at the front because i tested it when the brakes were cold.

It seems like a brake bias problem.

I have Project Mu SCR rotors & Endless SSS pads indentical front and rear.

Has anyone had this problem before?

Can you recommend a brake specialist in Melbourne?

Thanks

Stop pulling the handbrake lol.

Nah seriously I doubt it will be a brake bias issue at all. Are you running different size and brand tyres front to rear? When was the last time you changed your brake fluid?

I'm running the same tyres front & rear.

Brake fluid was changed less than 5000km's ago.

The problem has existed before that. I suspect it may have been after the brake master cylinder was replaced because it was faulty.

cool. you may have a silvia one on there. theres a part number stamped on the end of it. like 69f, or 05u etc etc the s15 one is the same a gtr one but sends double the pressure to the rear brakes. you need to peel back the alloy cap on the end of the master. just poke a screwdriver thru it. then theres an 8mm allen key. un do it and shorten the spring or use a gtr one. if not just keep shortening it till it doesnt lock up.

ive got the exact oposite problem. my alcons up front are to grippy compared to the ap,s on the rear lol.
