truck has been sitting for a awhile, and i get in it to back it up and no brakes, pedal goes right to the floor. i sit there and pump the brakes and they get alittle firm them go away again. ive always have had a leak on the pass. side rear drum but thats been that way for a year or so. i topped off the mc resivor and still nothing. i also pulled the hose off the brake booster to se if my vacuum pump was still working and i still have vacuum. so any advise?

 

maybe your brake lines swelled and its leaking internally??

 

prolly need to bleed em.........start with the furthest away from the resivor

also sounds like you need 2 new wheel cylenders for the back whilst yer at it

 

May as well flush the whole system while your at it.

 

Bet you had to replace the master cylinder??

 

What's the good word!!

 

Zach has the Mrs. been poking around under the hood of your truck lately? Do you have a large life insurance policy? Not pointing any fingers here......















Seriously though brakes are good I hope you got it fixed!

 

Hello Zach, hello Zach!!!

 

AW shucks, just put a rivet in the hose at each cylinder until you get a pedal. If no pedal obtained, the MC is bad. Please post travel intentions so I can stay off highway.
Just kidding!!!
Replace both rear wheel cylinders and MC. Now you may be able to do final diagnois if not completelly resolved by these repairs.

 

Zach, you can reopen the thread and update when you get the chance.
