Rear brake caliper problem

I replaced the rear wheel bearings last week. I also put new rotors and brake pads on. The right rear wheel is having problems with the caliper not releasing completely. It smoked quite a bit on it's maiden voyage.

So, if I have to replace the caliper & probably the rubber hose also, where are the most affordable places to shop?
thanks,
Mike S

Re: Rear brake caliper problem

Are you sure the caliper is the problem and not the parking brake shoe? Also is the hose to that caliper not twisted during installation, which could close the hose internally e prevent the fluid to flow back? Caliper sliding pins where lubricated?

Re: Rear brake caliper problem

I will check tonight to see if the hose got accidentally twisted. I did have a great deal of trouble installing the brake pads into the caliper....they were too thick to fit into the space, even with the caliper spread as far as it would go. After I was able to get them into the caliper, there was adequate clearance to the rotor.

I know that the emergency brake shoes are not the issue, as there is a lot of wear already on the face of the rotor where the brake pads have been rubbing (by comparison, the left rear wheel still looks new. The rear seal had been leaking on the right side and the E-shoes were saturated with oil.

Re: Rear brake caliper problem

I know that the front (Akebono) calipers have phenolic resin pistons which will not corrode, but the rear ones can be iron ones. I would check the piston to see if there is any corrosion on its surface, which could make it difficult for the piston to go back into the caliper (besides the fact that it will damage the seal). It can also happen that the brake hose will close of internally and keep some pressure on the caliper after the brake pedal is released. You could just open the bleed screw on the caliper when pushing back the piston and see if it then moves in freely.

Re: Rear brake caliper problem

I just did total brake package with power stop slotted/drilled rotors but the back brakes on the WK2 are so small and from the pad wear are rarely used except when steadying the jeep in a hard stop.

I replaced the pads but returned the back rotors as the Power Stop modems are also vented. The caliper is so small it wouldn't fit over the vented rotor. After looking at it, not a big deal but they are some really low budget calipers and rotors.

I would first check to see if you twisted a break line. Only then would I consider replacing the caliper and rotor system. Really that rear brake is just for stability much like in your motorcycles. 95%+ is the front brake unless you are towing. I don't tow at all and have the limited sans trailer hitch.

If you tow then I would look into the best you can afford.

Re: Rear brake caliper problem

I have been having the same issues with the rear brakes. They will both "drag" although the driver side is worse. I have read a few places that indicates caliper problem/maintenance/slide pin, collapsing brake lines, bad fluid/water boiling, and blocked/restricted return flow in master cylinder. I have not researched any TSB or recall info. I have not received any recall either. All I know is it is difficult to duplicate, happens more in warm 80+ humid weather, and is a PITA. I am thinking of replacing both calipers and brake lines (stainless braided).

Re: Rear brake caliper problem

Brake squeal is my issue and I've been to the dealer and they put that brake quiet on it but to no avail. I'm thinking of switching to ceramic pads as it seems those factory pads are just too cheap. Mind you I have 16,500 on my jeep 😳

Re: Rear brake caliper problem

The Power Stop rotors came with the carbon fiber/ceramic pads. They have a break-in process that needs to be done and a small tube of lubricant in the back of the pads but no noises at all. The break in requires 6-8 aggressive stops from 40mph in a row. Then let the pads cool a few minutes. You will smell a coating burn off and I think it cures the lubricant in back. Then medium, steady breaking from 20moh repeated another 6 times. I would find a good side road because it looks funny to people that have no idea what you are doing. I bought my brake kits on Amazon. Very happy even though I did return the rear rotors. Serious heavy duty stuff. The front rotors were huge but slotted and drilled have been on all my motorcycles and they never fade.

Re: Rear brake caliper problem

The Chrysler pads are terrible and a obvious way for them to cut costs and not put better ones on the jeeps.

Did you replace the brake hoses? What was the price you paid? Did you use the stock calipers? Yes seating/breaking in the pads is a process and will make you look like you don't know what you are doing.

Re: Rear brake caliper problem

I didn't replace the brakes hides as they were just fine. I considered it, but the only place that is not SS is from the wheel well to the caliper. The prices were pretty high but had rotors and ceramic pads. I think around $169 for the front. The rear was $10 less but since I didn't replace the Calipers I had to return the rotors on the rear as the Jeep caliper in the rear is small and the rotor wouldn't fit through the caliper at its widest. However the old pads were barely used. I think the only use is to keep the Jeep stabilized and in Emergency situations. The least wear on a set of rear pads I have ever seen. The rotor us non-vented and thin compared with the hefty fronts, even the OEM, which were out hefted by the power brake rotors. Glad the front calipers were beefy enough to fit everything just fine. Still all is working great, quite and smooth.
