Hi my brakes keep sticking on after a blast to the point where you can't move the car ?

If you leave it for 10 mins after they gradually un seize them selves ???
It's all four brakes ? Help

Foot pedal binding and not returning properly?

Push rod too long, dual or single master cyl?

Should explain a little, the above can cause the pads to bind slightly and cause them to heat up, as they get hotter and hotter the brake fluid will boil and expand causing the pads to apply harder making the problem worse, you leave them to cool and the problem goes away, temporaliy.

Cheers

Jack the front of the car up, press the brakes hard, and then release.

If you now can't turn the front wheels by hand then you have a problem. I would start by disconnecting the master cylinder push rod from the pedal so you know that the pedal has no influence in pre-loading the push rod for any reason.

See if you can turn the front wheels now?

I had this problem when I went for my very first drive, it was the brake pedal that needed adjusting as it was putting on a tiny bit of pressure the brakes which, over the course of a few miles, caused them to overheat

The pistons in the master cylinders need to be able to return fully, 9 times out of 10 the problem is the stop washer at the pedal end of the master cylinder not allowing the push rod to return fully.

Or, as in my case. the push rod is too long - fine when cold but all of the clearance disappears when the brakes are hot, so the master cylinder return port is still closed and it holds the brakes on.

You can try hooking your toe under the brake pedal and pulling it back when this problem happens. If your brakes free off immediately then it's likely that the pedal isn't returning to its home position fully. The pedal needs to come right back to let excess fluid back into the reservoir, and if this doesn't happen the pressure will build up a little bit more with every brake application.

Do you have a return spring on your brake pedal? Mine has quite a hefty one that helps to pull the pedal to the 'off' position - with the power of leg muscles and the leverage in the pedal the spring isn't noticeable at all.

Just a longshot here, but have you bled your brakes recently? It could be due to water in the fluid, which boils when the brakes get hot, giving the kind of problem you are experiencing.

Brake pedal not enough free play
brake fluid level too high

I'm away all weekend but I'll try a few things when I'm
Back ...


The strange thing is I can drive it normal for 50 miles no issues but if I go for a blast it does it ????
