Front Brake Dragging

Some of you may recall we've been shopping for a WJ with fewer miles (ours has 250k now). We found a '99 with 53k on it & made a deal yesterday.

They had replaced a front axle (cracked rubber boot) & the front brakes. I thought the brakes was odd since so few miles on the vehicle. Anyway, we get 30 miles from the dealer (we live 4 hours away) & sonya is flashing her lights at me to pull over (we rode up on the motorcycle). When she pulled into the lot where I had stopped, the right front brake is smoking bad. This did not reveal itself when we test drove the car.

My guess is the rubber hose has collapsed & not allowing the caliper to release, or the caliper was corroded & the new pads put the caliper pistons into a place where they are jamming. Any other possibilities?

Fortunately, a good friend lives close by & we limped the thing to his house & left it last night (finally got home about 1am this morning). The dealer doesn't have his own shop & is willing to cover the costs of repair. I plan to take a new hose, rebuilt caliper, & rotor with me. Anything else I should look for?

Re: Front Brake Dragging

Check to make sure the pins aren't seized in place. Mine did this and it caused major issues. Not to the point of smoking but it warped the rotor like none other and when I pressed the brakes on the highway it felt like the front end was going to fall off. It got hot enough to "rainbow" the metal rotor.

Well, 32 dollars for the hose & 50 dollars for the caliper & we are back in business. I wasn't sure which was the root cause, so replaced both. The dealer is to reemburse us for our expenses. The new rotors that the dealer had installed did not warp fortunately.

Now.....to address that passenger front window that doesn't work properly (will go down but not all the way up.....the dealer had also had that "fixed".

Re: Front Brake Dragging

Ok, so now the left front brake is dragging. Coming home from work I noticed a shimmy/shaking. I thought maybe I had a tire going bad, so I pulled over to check it out. As soon as I stepped out of the car, I could see smoke coming from the caliper. I live in a rural area, so was able slow down & ease my way home.

I just received the replacement parts (not sure which is bad, so am replacing the hose and the caliper.....66 dollars for AC delco parts from RockAuto).

Now, the 64 dollar question....what size is the allen wrench needed to remove the caliper? It's smaller than 8mm but larger than 1/4. I don't know that I have any odd size wrenches.
thanks,
Mike S

Re: Front Brake Dragging

So you don´t have the Akebono calipers in the front. Most probably the hex size is 7mm.

Re: Front Brake Dragging

I guess I was too impatient last night when I started working on the brakes....after I went back outside I reached into a box of loose allen wrenches I have & the first one I picked up fit the bolts (there was no marking on the wrench & I forgot to measure it to see what it really was....could be 7mm....). The rest of the job went smoothly. I was a little nervous about the steel brake line which attaches to the new line as it was a little rusty looking , but it broke free & caused no issues.

The new (rebuilt) calipers use 1/4 inch allen head bolts. I do not know what brand either of the calipers were (both are dual piston).

Re: Front Brake Dragging

When they have a large spring clip on the outher side, then they are TEVES. Without the spring its AKEBONO.

Re: Front Brake Dragging

Mine have the large wire spring. The new one that came with the caliper was not formed properly & rubbed on the rotor. The old one was in good condition so I re-used it.
