brake trouble

Ok Thanks. If it does it again i will give that a try. What i ended up doing was using two thermostat gaskets in between the master and the booster and it hasn't done it yet. (knock on wood).

79bird Ok I was just watching this show called Chasing Classic Cars last night and the same thing happened to them. So the cause for them was that the Master was bad and the booster locked up, they bleed the front brakes ONLY and it was good to go (except the brakes were out in the front). Might try that

Felpro makes a Chevrolet thermostat gasket out of plasic with an O ring seal. Ir's the same bolt pattern as the master cylinder, and about .100" thick. You can use one of them as a spacer.

1pickup Just re-read your post. Sorry, you did say between master & booster.

1pickup My bro had this problem on his rat rod. The problem was that the pushrod for the master was TOO LONG. He had put an S10 setup in his '36 Plymouth. Apparently, the firewall was thinner on the car. Did you change anything else in this area? Adding a washer would probably be making it worse, unless you added them between the master & firewall.

brake trouble

I have looked at the Hydro boost and i don't see any adjustments on the push rods does anyone know if i could put washers in between the master and the Hydro boost to make up the space so it wont keep doing this
Thanks

yup your right i opened the bleeder screw and it released

Thanks i will check the Hydro boost push rods and see what i can come up with i will also check the master cylinder to make sure that it was the right one for this truck

Thanks again

enjenjo Changing brake line size will change nothing. Pressure on a hydraulic system is the same throughout the system regardless of line size.

Next time the brakes lock, open a bleeder in front. If they release the problem is the fluid is being held in the front, rather than released back to the master cylinder. The cause can be a misadjusted brake pedal, misadjusted booster pushrod, wrong master cylinder, something in the line acting as a check valve, or defective brake hoses.

does anyone know if a Hydro boost would cause calipers (both front) not release

Question what about if i run a 1/4 inch line to the rear brakes . Would that release enough pressure on the front brakes?
