The brakes feel like they're sticking on my 86. It seems to be happening when it's hot and I'm in traffic. Has anyone else run accross an issue like this?

 

OK, its hot out. Really hot out.
Do you have the original calipers and hoses?

I'd bet one of your hoses is borderline and is swelling with heat and pressure.
Or one of the pistons is "hanging" and the caliper needs rebuilt

 

Thanks for responding, I'll check the hoses and calipers.

 

VBP is having a great sale on the stainless lines. I just got my set. I know that one of mine is hanging since that wheel always shows brake dust after washing the car.

 

My 1992 lt1 is doing the same thing.

When it is hot out (85+) my front brakes start sticking after I drive it a few miles in traffic.

I turned the rotors and replaced both front calipers, brakes, and brake hoses.

The brakes are still sticking.

I live in Orlando, so I took the car to Corvette Masters in Maitland.
They first said it was the Booster. So they changed it. That did NOT fix it.

They then said it was the Master Cylinder. They changed it. That did NOT fix it.

We then decided to change the Brake Pressure Modulator (BPM). That still DID NOT FIX IT!

At this point, I am exhausted and out of ideals. Please help . . .

 

Sounds like an expensive "lets throw parts at it" shop to me.

Now that you changed all those parts look at it logically:
something in the brake lines that feed the caliper (s) is acting like a check valve.
I'd start checking the hard lines from the master to the BPM and the BPM to the brake hose.
Look ok?
geet a brake bleeding bottle, a helper and some brake fluid (I use valvoline syntec about $9 a qt).
Go to the bleeder screw of the sticking caliper (car in air, tire off)
hook the hose to the bleeder screw
open it up - does fluid start leaking into the hose and into the bottle?
close the bleeder, have helper steady press and release the brake pedal until its really hard to push. have them maintain pressure on the pedal. Open the bleed screw - did fluid "gush" into the hose or trickle?
Close the bleeder screw and have the helper let up on the brake pedal.
Repeat two more times and top the master cylinder off with fresh fluid.

If you have another caliper sticking repeat at that caliper.

After you put the wheels on and the car off the jack stands take it for a drive. Before you move the car use the brake pedal a couple of times (trust me). move slowly and make sure the brakes work before leaving the driveway.

Any caliper that just dribbles when the pedal is pushed - your blockage is in the lines feeding that corner.

Good luck!

 

Has anybody checked their actuator rod from the booster. If it is marginal and set to long, when things heat up and expand it can put pressure on the master and never let it completely release.

When this is happening jack a front wheel up and see if it is dragging. If so, pull the master back and adjust the rod about 1 turn (or 2 max for starters) and see if it makes a difference. You need to hold the rod and turn the adjusting nut in (right)

Try it for a day and see if it makes a difference. No money invested here.

That’s not the usual comments I hear about Corvette Masters.

 

I’m trying to fix the same problem, if you changed all those parts and the problem remains the only thing left is to check the clearance between the slave cylinder and the booster shaft, just loosen a bit the slave cylinder 4 bolts to create a gap and drove the car to see if this solve the problem, if so put a spacer or try to adjust/retract the shaft
