I was replacing my ball joints and when i removed the right front caliper it came apart. When i first got the trruck one of the front calipers stuck a couple times. So im looking to get a used one from a junk yard and wondering if i should just replace both? I will also be replacing the rotors with new ones because i can deffinetly tell those are warped.

Today i just notice the inside of my right rear drum lookes like its leaking so it looks like i will be replacing a brake cylinder too

 

You're better off replacing both with new ones.

 

Always replace calipers and wheel cylinders in pairs. Even of one caliper is ok when you replace the bad side the new caliper is more efficient and has less resistance so it brakes better than the old caliper which causes a pull when braking. Same idea with wheel cylinders in the rear plus the bleeders on them are usually rusted and round off when you go to bleed the brakes anyway.

 

Ok, it's always easier to spend someone else's money. but.....

For one, I would never buy brake parts from a junkyard unless new was unavailable. (reman works fine too) I would replace the calipers in pairs, although any difference between a new and old would really be negligible. Many times I've replaced one side and not the other and never experienced a pull. Wheel cylinders are the same story. Besides, consider the argument that they've both seen the same service life. If one is bad the other probably isn't too far behind. I even replace my bulbs in pairs.

Now, given your situation, it wouldn't be much more to invest in both calipers and wheel cylinders. Yes, it doubles your expense, but it's not unreasonable. While at it I would make sure and do a good brake fluid flush. Keep going until you get fresh fluid out.

Just out of curiosity, how are you able to tell your rotors are warped? Brake pulsation? You didn't elaborate so I'm asking. New rotors are a good idea anyway. I hope you're following all this up with new pads. You may want to check the hoses as well for dry rotting. Brake hoses last a lot longer these days as the industry is using much better rubber compounds. Remember the days when you were lucky to get more than 60k out of a set of cv boots? I do.

 

The money you save on used brake parts, you'll spend when you rear-end someone.

 

I've replaced one caliper a couple times and experienced a pull is why I said it. Apparently it won't happen every time though if it didn't happen to you.

 

i feel some pulsing through the brake pedal. Thanks for all the help

 

There is a right and left side caliper right!

 

Yes.

 

agreed. def better to replace both.
