Re: Brake calipers..

As soon as you remove the brake hose from the caliper, some fluid will come out and air goes in. Also the new caliper is probably without fluid, so some bleeding has to be done. Just bleed until no air bubbles come out anymore, but take care that the reservoir doesn´t get empty.
Depending on how long ago the brake fluid was changed, it could be a good opportunity to change all fluid. Brake fluid is hygroscopic, so it will attract humidity from the air. This water can cause corrosion inside the brake system, but also when the brake fluid gets hot, it can form vapor and the brakes gets spongy and the brake action gets less. You don´t want to find this out when you are on a hot day going downhill..............
Brake fluid should normally be changed every 2 years, to prevent those problems.
Also the sliding pins from the calipers need some grease so now and then, just to prevent them from binding. The manual mentiones every 18000 miles for normal maintenance schedule.

Re: Brake calipers..

One more question here from a guy that hasn't done it in a while--To bleed the front calipers after install=--should the engine be -off--or running to use the brake booster?

Re: Brake calipers..

Everytime I've done them it with the engine off. It also makes it easier to talk/listen if using a helper.

Engine off... Realistically gravity bleeding does pretty well. To do this replace the caliper on one side, crack the bleeder open, top the reservoir off then go and replace the other caliper. When you have that one replaced check for brake fluid flow from the first one. if you have a constant dribble, close it and give the other side done time to bleed. Last step is to test the brake pedal before you put the wheels back on (incase furtger bleeding is required, its easier with the wheels off).

I do all my caliper replacements this way and most of the time it works every time

Re: Brake calipers..

you will have to bleed it as the caliper will be dry, but not to bad... should just take a few min to get done... when i powdered mine i had the whole truck bled in about 10 min, but that was with someone there helping me... simple swap

Re: Brake calipers..

Well--new calipers installed, everything cleaned up--only thing left is bleeding the new front calipers-

-if my wife is still feeling under the weather, I'll ask a young neighbor lad over to help--I'm trying to show him some mechanical things anyway--as he doesn't have a father in the picture.

Thanks for all your advice, folks--I'm glad I found this site , specific to my questions--

Yes, you are going to have to bleed the front's

Basically replace the calipers fill the brake fluid up let it gravity fill the calipers till it starts to run out then proceed to bleed normally


DO NOT I REPEAT DO NOT LET MASTER CYLINDER SUCK AIR!! If it does it's a dealer only trip to have the ABS pump and shit cycled.

Re: Brake calipers..

Hey guys doing some brake stuff as well. I have the ATE Calipers. I think you can also tell by the brake master cylinder mine says ATE as well as the calipers I think my jeep was made in Sept 2000. Anyhow how I remove the wire pin retainers(whatever you call them). I spray penetrating fluid on them and use a set of good needle nose with a flat blade screw driver/ carefully wiggle/and pry you could use a little heat if need be small torch lightly. The Bolt PINS/ the ones that move the caliper back and forth. I am removing mine here in a bit. Yes they use a Torx bit(stupid JEEP). Should have used Metric Allens to keep it all the same! I am going to take them out and clean the surface/light polish them and then reinstall them with a light application of anti-seize. I also put a dab of anti-seize on the retainer pins ends. As well as the wire ends. This helps for the next time this assembly comes apart next brake change. It goes pretty smooth make sure use brake clean on everything after final assembly.

Re: Brake calipers..

I was replacing my front brake pads and rotors and when I removed the lower bolt holding the caliper support bracket, it was stripped and had been put in with JB Weld or some other liquid steel product to glue it in place. I bought that Overland new in 2002 and it had all its servicing done at that same 5 star dealer. The only people who had that bracket off before me was that dealer when they replaced the hub on that side. As soon as I saw it I knew some hero mechanic put an impact driver on it and stripped it. Personally I use a torque wrench. I had words with the maintenance super, but I could not prove they did it. I think at some point they decided I needed to trade up and started destroying my Jeep. Well, when I do trade it will be for a Toyota. My Tacoma has 220,000 miles on it and is just fine.
