replacing brake pads

[757Hokie83]

i think when i get home tonight i will be replacing my brake pads and rotors on the jeep(probably should have done it a week or so ago)...my question is, if i dont open the bleeders, or disconnect any brake lines...do i still need to bleed the brake lines?

I could be wrong but I don't think so. Again, I could be wrong about this too, but if your pads and rotors are wore down, you'll probably have to relieve some brake fluid pressure in order for the new pads to fit. Atleast in my limited experiences changing breaks that's been the case.

 

[Hank Kingsley]

Nope.

But you're going to have to push the piston's back somehow and that forces fluid back into the reservoir so you should ensure it doesn't overflow as brake fluid is corrosive.

On my car up front you can push the pistons back with those clamps woodworkers use to hold things in place.

At the back you have to rotate them in, not push. So I have a tool I put on my electric drill that does that.

And fluid does get dirty so sometimes a flush is a good thing.

I've only done brake pads once before and it was some years ago, but I think I can use a big c clamp to push the caliper piston back in

I probably am due for a flush, but no time tonight

Mine are those pistol grip rubber encased ones.

I use the old pad up front to push on rather than right on the piston.

Have done it many times without bleeding the lines. Just need a C clamp to push the pistons in.

 

[LucklessPadresFan]

I never bleed the lines. Hell, it is a lot less messy than changing the oil.

bring it to a ''professional'',.....tell him you'll pay ca$h, knock down your bill.

No need to bleed the lines, but take the cap off the fluid reservoir before you push pistons back into the calipers. I read somewhere that you could fuck up your abs system if you don't take off cap.

Word. Thanks. I assume this is to relieve pressure? This won't allow extra dirt to get in the brake fluid?

Getting ready to take the boy to day care (in moms car), then get started

 

[noonthirtyjoe]

You got to remove the cap so the pressure from squeezing the calipers has somewhere to go. It will over flow the reservoir.

Not unless you have dirt on the underside of your hood or wind is blowing crap all over.

As I said, if the reservoir is relatively full you should maybe pull some out with a turkey baster to avoid overflow. A surprising amount goes back when you push the pistons back.

had a little bit over flow when doing the second set of brake pads, not too much though. replaced brake pads and rotor on driver side, and brake pads on passenger (autozone only had 1 rotor in stock, will be going back to get the second tonight). Although the passenger side rotor isnt nearly as bad as the driver side was

new pads vs old:

 

[757Hokie83]

took me a little longer than i thought it would to get it all done and cleaned up...including set up, and clean up, probably about 2 hours or so

dang man, where those things chirping pretty bad?

A little overflow is to be expected, depending on what your brake reservoir lid looked like might have needed to pop the little rubber indentions back up.

Now that you have replaced both sides at teh same time, keep an eye on the wear the next time you change your pads. Could be a case of one side dragging. Will screw up your rotors, screw your gas mileage, and could cause brake failure if the calipers are getting too hot.

shit no, straight up metal on metal grinding, lol. got progressively worse every day this week, i actually was going to bring it to a shop near my office (42 miles from home) this morning to have them do it, cause i just dont have the time any more, but by the time i got home last night, i had decided i wasnt driving it another mile before i changed them

You saved yourself 2 - 3 bills minimum. Great job.

well the guy i had that was gonna do it is a buddy and was just gonna be $50 labor, but i do enjoy doing it myself, when i can find the time

My wife had a left rear caliper on her Maxima seize. The whole wheel got smoking hot. I was concerned about the bearing.

Lordco had to order one for the next day delivery. So I jacked it up, removed everything I could and left the caliper hanging. The next day I picked up up the new one, and had it installed inside of 20 minutes.

The hardest part was the stupid emergency brake stuff which complicates the rear way more than the front.
