Brakes Are Briefly Sticking After I'm Off The Pedal

[robj]

I had a track day, and the brakes seem to stick for about a second or so after I've come off the brakes.

This only happens on the front wheels, and these are the only one boosted.

 

System:

 

front:

 

4pot hilux calipers

VH44 remote booster

1' hilux master cylinder.

 

rear

 

Standard RA23 drums on the t series diff.

 

 

 

I put a kit through the calipers, they were fine.

replaced the VH44 booster(ABS did this, they said it was faultly). Driving it hope, still the same.

 

 

If anyone has any ideas, let me know.

 

Thanks Rob J.

grease caliper pins with high super temp grease?

Is the both doing it or just one ? If its both, i'd be looking at the master cylinder. If its just one, i'd be more then just putting a kit through the calipers

Hows the pads ? As i found out with my old seca when the pads had worn down a fair bit (about half a mill from the metal) was that one caliper would stick

Really good idea, but being 4 pots they wouldn't have pins to slide on!!

 

Check the adjustment on you break pedal shaft as well.

Both front brakes stick. The pads have plent of meat left on them, but perhaps got too hot? Don't know if that could do anything.

Whats the brake fluid like ? Could have crap floating in it acting like a valve. Otherwise be looking at the master cylinder

if they where kitted you would hope they wouldn't have junk in them...

They have retaining/slide pins that go through the pad itself by memory

 

 

What master cylinder are you using Rob ? and is it very old ?

 

could be the residual valve in the master ? i 'm pretty sure it its job to relieve pressure to allow pads to release
