After a day of work I went home and started to overhaul my rear brakes.
Everything went fine except that one of those "pistons" fell out. Didn't think about it so i just put it back in the hole.
When it was ready to test drive the brake pedal went down to the floor but when i am pumping it gets hard and stays up.
Do i have air in the system?
Didn't have this problem before.



Love my dodge but not now haha lol

 

Thats actually not a piston. It's the arm. The piston is inside the wheel cylinder.

Does your brake pedal stay high and hard with the engine running? Not losing any pressure at all?

Does the pedal feel spoungy?

 

The pedal goes to the floor when the engine is on. If i pump a serveral times i get pressure and the brakes feels good. When having pressure the pedal is not spoungy.
Maybe i just have to adjust the rear brakes more? Will lift the car up tomorrow and check if i can spin the wheels when pushing on the brake..

 

After putting the drums on, did you adjust the self adjusters?

 

If you replaced the wheel cylinders which I assume you did in a brake rebuild you have to bleed them. Even if you didn't you should.

 

If you have to pump the pedal every time you start the truck, then yes, you need to bleed the brakes. If the pedal requires any pumping in addition to the initial pressure build up you already did, then they need to be bled.

 

Not giving us enough info to figure out your problem. The first time you start/drive the truck the pedal will be down to the floor until the brakes adjust and come into contact with the drum. The way to adjust rear brakes is to drive the truck in reverse and stop a few times. You can always do it manually. but it is more work.

 

I did not replace the wheel cylinder..
So if the arm fell out i shouldn't need to bleed? Right?
Will do the reverse thing when i get home.

 

Adjust them up manually first. Jack up the rear, and turn the adjuster wheel until the shoes just start to scrub a bit. If you turned the adjusters all the way in when you did the brakes, the backing up trick will take you from Detroit to Albuquerque before they are adjusted properly.

 

Did them manually now and now i've got pressure and the brakes are like before.
But i think i have some air in the system after the previous owner did the front brakes. Will bleed the system later and see whats coming out The pedal has always been little soft since i bought it..

HAHA
