Rear Wheel Cylinders

Are the rear brake wheel cylinders different (right/left)? "70 -1/2 ton"

Different angle where the line attaches.

Re: Rear Wheel Cylinders

I have searched the parts on line and from what I read the fitting thread sizes are different. One's 3/8 and the other's 7/16. Is that correct??

Thanks for the help. Just spent 1-#large on a valve job. Still patching more little stuff.

Re: Rear Wheel Cylinders

According to the books, both rear cylinders have the same thread. Angle different from right and left. Same with the front. 4WD trucks without locking hubs have 7/16" front cylinders, models with locking hubs have 3/8".

Re: Rear Wheel Cylinders

O.K., I'm just trying to buy the right stuff and here's what I found from NAPA and maybe that's what is confusing me.: ?right & left?

Those links didn't work. But I did a quick search of the NAPA site and see what you mean. They list two different size threads. My guess it is a typo. Just re-did the entire brake system on my '69 c-10 and both rear cylinders used the same thread.

Re: Rear Wheel Cylinders

Sorry about the links, but thanks for taking the time to chase 'em down. Gotta' get the right stuff - truck's my only wheels, so I'm stranded if the stuff doesn't fit. Off tomorrow, so time will tell LOL
