1 1/2 ton Brake help needed


Recommended Posts

I am having trouble with my 1 1/2 ton brakes. I have rebuilt the master cylinder and one wheel cylinder. I have a rock solid brake pedal, i left off just a bit and then it slowly fades to the floor. Weird thing is i have absolutley NO BRAKES at all. I have bled the brakes and have minimal fluid coming out. I disconnected the line before the booster and pedal went straight to the floor and squirted brake fluid everywhere. I disconnected the line after the booster and the same result. if i open a bleeder it should go to the floor quickly but it doesn't? Front two brake lines are brand new as well.

Did you have the booster rebuilt properly ? If not you should.

About 7 years ago, I put a brand new master cylinder on a 1949 Power Wagon that I restored.  The pedal would slowly go to the floor.  I pulled it and dismantled it and realized that this thing was made in Taiwan.  Feeling disappointed, I sleeved the original master cylinder with a bronze sleeve and rebuilt it.  Problem solved!

I hope this helps...

If the frame mount booster were to fail on the road....oh boy!

The engine vacuum will suck all the fluid out of the master cylinder while driving and guess what??????

No brakes! Been there twice ...done that twice.

You will see a HUGE cloud of white smoke growing behind you and cars disappearing in that cloud!:eek:
