I was going to replace the rear brake shoes today, and didnt run into any problems until i was trying to get the shoes in place on the passenger side, and when i tried to push the shoes together to center them a little bit and make it easier to get the tension spring on, brake fluid shot out of the drivers side wheel cylinder (the upper one). My question is, should i replace both wheel cylinders while im at it? Should i rebuild them or just buy new? Are any brands better than others? At least i know part of the problem with why my brakes are so s***ty, im thinking it was out of adjustment too, the shoes were really worn.

Also, a more recent and irritating development, i was cleaning off the hardware i pulled out, and one of the adjustment rod dealies was kinda rough on the threads like it had dirt in it, so i unscrewed it all the way and now i cant get it to thread back in. Any suggestions, it wants to start and then it pops out of place. I was smart and didnt unscrew the other one all the way, why did i have to do that last one that way.....

Thanks for any help.
 
I am almost positive it is a reverse thread on the adjuster. It's worth a shot anyway. I have always replaced wheel cylinders in pairs. That was expensive on my 4 wheel drum 74 fj40 8 wheel cylinders total.

OEM is the way to go.

I just ordered some beck-arnley ones from advance, i didnt have time to wait for shipping on OEM (plus i straight up cant afford them), was gonna go with bendix but it was 20 bucks vs. 30 for the bendix. Hopefully it turns out fine, it sure better, im spending all my damn money on brakes.
 
Napa has rebuild kits for those cylinders. About 5 bucks each...
 
just a hint . when i replaced my wheel cylendars the first one i disasembled everything. then putting it back on i discoverd

that if you just take the twp pins that go threw back of drum plate and do alittle wiggling and palm smacking you can pull the brake shoes off with the springs tensioner and everything still in place then put it back same way
 
I already have the whole thing apart, i found the leaky cylinder when i went to put new shoes on. Im getting the new parts tommorow morning and should have it done soon thereafter, after taking it all apart i realized its really not complicated at all. The funny part is the truck is sitting on jackstands in my apartment parking lot right now. The management must hate me, ive got a big ass truck on jackstands in the middle of their parking lot, a total of 6 tires on my porch, and im a damn dirty hippie.
 
but what i was saying was instead of fighting with the springs and such putting one piece at a time on . If you assemble the brakes while sitting on the ground place springs and adjusters where they go ahead of time. it will save you alot of time . or atleast it did me. putting the asembly back in i started by sticking the beleve it was the spring that rides under the cylender first then everything swings in place. And u only have to adjust the tenssioner and put the two pics from the back plate threw with retaining clips.


I bought my cylenders at autozone for 15.99 each
