Post subject:  Replaced rear caliper. Question on bleeding brakes
Just a quick question. I ended up replace the passenger rear caliper yesterday and was wondering what the proper way to bleed the brakes were. A book we had suggested that on a non-ABS(my jeep does not have ABS) system you only have to bleed the line that you opened. My dad insisted on at least bleeding the back 2 brakes(which we did.) So my question is, which way is right? Or do we really have to bleed all the brakes? Sorry for the dumb question, I can't seem to find a right answer. :banghead:

I would have bled left and right rear also. Just how I was taught to do brakes.

I did do the left and right rear. So I should be good then? No need to do the front too? :?

You can get by with just doing what you replaced BUT Really if you want to do it right brake fluid needs to be changed out just like other fluids. It gets moisture etc in it.
Start with the right rear, left rear, right front and finish with the left front, making sure you get clean fluid throughout the system

I'll have to do that in the near future. Right now I'm just happy to have brakes. :-)r

Ditto. Any time you change a major braking component it is a great time to also flush out the old fluid and get some new in there. It only takes a little while longer and a few more $'s to get it done so why not.

When I replaced my rear caliper, I only bled the side I replaced. Your dad may be correct that if you drain enough fluid and airbubbles work their way WAY up into the system, that it might be a 'best practice' to bleed both.

However, I bled just one side and haven't had any issues. And in the process of bleeding you can see how much air comes out of it. When I bled mine, only a few bubbles came out the first depression of the brake pedal. So very little air got into my system.

Edit: Now that I read the responses, yeah, I guess if you're taking the opportunity to change out the old fluid completely from the system, then you're gonna bleed all four.

x3 on the flush out old, gravity on all 4 used to be the absolute proper way to bleed all air, then again times and technology change
