ok i had a blown rear passenger side wheel cylinder...everything was stained...replaced the wheel cylinders with the chev 1 tons and put in new shoes and bled it...for two months it was fine...inspected it every 2 weeks...clean as a whistle...and now its wet again...another blown cylinder...what could be causing this??

 

Thats what you get using Chevy parts on a dodge
I think that you just got lucky and got a crappy part.

 

well lets hope so..its the same side..first time it was the dodge cylinder and now even the bigger chev cylinder blew...ticking me off..those shoes are practically new...

 

Yeah mom's got a 2000 and has had nothing but trouble with the rear brakes
Errrr "Breaks"
If we ever solve them all I'll let you know.

 

im just trying to find what would cause a blown brake cylinder besides just a crappy part?

 

I can't think of anything,if the one you put on is the right size.
Sometimes if you get the drum reeeeaal hot the thing will blow.

 

My guess is the brakes were not adjusted right and the piston came out too far?

How are you adjusting them?

 

How about self adjusters on the wrong sides?

 

As Geico and Wanna said were brakes adjusted properly or self adjusters not working. I wouldn't toss out those pads, hit them with some brake clean and emery cloth should be fine after that.

hmmm well ive been adjusting them manually...never thought of the self adjusters as being possible causes...so lets say they could be on the wrong side.. or not working right...how would that possibly cause the blown cylinder?

ps i dont think i can really salvage the brake shoe...they soak up with the oil don't they?

 

When you say "blown cylinder" do you mean the pistons came out of the bore or the seals failed?

Don't worry, any brake fluid that doesn't wash off the surface will bake out soon enough with some hard stops - just remember to burnish, not glaze!

 

seals failed....new shoes cost me 20$ today at autozone ...just i just got em....new cylinder too...i dunno...20$ isnt so bad...we shall see...i gotta check if the adjusters are working...or maybe they're seized or something...the hardware for all that cost 7$ so no biggie...

 

If the previous cylinders blew out so quickly, don't use the new ones until you've found and corrected the root cause, or you'll do it again!

 

since it is an 11 year old truck it could be the flex breakline to the rear. They can breakdown inside and hold pressure on the cylinders.

 

maybe grit in the juice? just a thought
