TTA Front brakes locked on
TTA Front brakes locked on
I have a 1989 Turbo Trans Am that my father bought new. It has been sitting for about 20 years. Both front brakes are locked up. I opened the bleeder on the driver's front caliper. Little dark fluid came out, but the wheel was free. I was unable to bleed the wheel even using vacuum. The brake pedal is pretty stiff. I'm thinking either the master cylinder or the proportioning valve is stuck. I'll power bleed it once I figure out what's blocking the fluid. Any suggestions on which master to get, as well as which brake hoses? What about pads and rotors? I looked on Rock Auto, but with it being the same as 1LE, it seemed there's a good chance to get the wrong parts.

I'd start by changing the 5 rubber hoses. Sadly, they normally are the 1st to go. Nothing but china parts anymore unless you get lucky and find NOS or go stainless braided.

Re: TTA Front brakes locked on
It was both front hoses. Regular non 1LE hoses are too short (19" vs 21 1/2" for 1LE) but will bolt on in a pinch. I wound up with the proper hoses from an eBay vendor for $36 for the pair. I also bought rotors and pads for the front. TireRack had Stop Tech drilled cryo rotors for $160 for the pair, so those'll go on after I get a few miles on the car.

Good to hear, keep the stock rotors, they don't warp as bad as the aftermarket ones do
