Re: I need to service my emergency brakes.

When I mash the pedal it holds great, I just wasn't putting enough force on the Emergency Brake Pedal.''Wimpy"

That was over a year ago but haven't had the time or patience to fix this.
I seem to recall that most star adjusters are simple left-hand threads for both sides (so the same parts can be used on either side). So on the driver's side you would most likely have to spin the star 'downward' and on the passenger side you would have to spin the star 'upward'.

Just think about how you would loosen a nut/bolt combination if it was inside the 'drum' of the disk brake hat. You need to loosen or expand the 'bolt' that spreads the brake pads.

If you are doing the 'adjust and road test' method, I would advise only turning 1 or 2 clicks each side and testing. May take longer, but less chance of over-tightening.

Unfortunately... I'm old enough to have worked on drum brakes, but it has been quite a while since I've done any actual work on drum brakes.

And to Jeep/Chrysler... No auto adjusting e-brake? Seriously? Morons.

Thanks a lot for the advice. I'm definitively going to try that once we get a warmer day on a weekend.

Re: I need to service my emergency brakes.

This is an old thread, but question to anyone who could answer...

I have almost no e-brake catch when I mash on the pedal at 53K miles... Also, this seems to be related to a squeak I hear at low speeds that is clearly "rotor" based, but not stopped by gentle main brake application (the discs) so it is not a sticky caliper. It does seem to go away immediately when I push on the e brake when moving slowly, so it is the e brake, I think.

I'm going to try adjusting the e brake. But is there some explanation for the squeaking by a e brake that is too loose? I can't figure out why something would be rubbing if everything is worn and loose.

thanks.

===

EDIT FOR UPDATE..

I removed the RR (passenger rear) rotor and cleaned everything, adjusted by guess probably 1/2 to 1 full turn. It was very dirty and hard to remove and once I centered the drum it went on really easily and clearly turned easier despite being "tightened" - this was without brake applied of course..

I could tell the noise was from the RR and now it seems gone on one test drive and the brake holds (stops on a hill, even) better but still not great. Didn't have time to do the LR, but may try just using the site hole. Although I could not honestly get to the RR one enough to move it without removing the rotor - and it needed clean big time anyway. Hope this helps someone. I'll repost if issues arise or I get around to the LR and re-test...

Still unsure of whether or not there is a way to "tighten" the cable or if that is "self adjusting". Info would be appreciated.. 2012 WK2 V8 with tow package..

Re: I need to service my emergency brakes.

So as you can see from above, I've spent some time with my e brake lately...

It still kept squeaking. I realized my options were to somehow grind the rust off the edge of the drum or buy a new rotor. I had two people I trust say just buy a new one so I did for $55. Problem fixed. The only other thing I heard was that one of the shoes could delaminate and cause squeaking but mine inspected fine. Of course I live in a salt-infested part of the world. I'm still surprised in 4 years a rotor is toast.

Hope this helps someone down the road.

Re: I need to service my emergency brakes.

Update #7... E brake pedal went to floor without any effort... So I had to remove the e brake assembly on the right rear - the one most hit by salt and slush...

The punch line. It was the metal connector to the cable at the brake, this is a hinged piece that was frozen by corrosion. Had to remove the e brake pads to get to it. Cleaned and lubed and like new.. No need to have replaced the rotor... Hope this helps someone some day.

I know this is an old thread by why make a new one. I am having a similar parking brake issue. Cable seems fine as I engaged the brake and it is pulling on both sides fine. So I'm wondering if I need to do the adjustment as described in this thread. Problem is, I can't for the life of me locate where the adjustment screw is or the rubber plug that covers it??? Is it on the back of the brake assembly somewhere? Do I need to remove the wheel to get to it? Thanks in advance!

Re: I need to service my emergency brakes.

Lost my server, lost a detailed write-up of this twice... Sorry... can't redo..

I had to remove the wheel, caliper, rotor to get anywhere. May need to remove the mechanism of the E-brake to get corrosion out. I ended up carefully spraying the entire brake (NOT THE PADS!) with AMsoil metal protector, and using syn brake grease on the backing plate / pad firction spots. Had to adjust the star with both rears up, car in N, airlift disabled, still the car was unstable and wanted to roll.. Be careful.

Consider new rotors if you are going to attack this, 100$ for two isn't bad non-OEM.. My rear pads at 70K are still OK, about half gone or less.

Re: I need to service my emergency brakes.

This is from another discussion that I posted this in:

I bought a new drum brake adjustment tool, as the old one I had was OK for setting regular drum brakes, but was too large to fit inside the rear rotors, to set the parking brake. I bought an AMPRO T71558 tool, and it fit the bill perfectly.

I set the tool, then adjusted the parking brake shoes so there was 0.025-0.030" of clearance, using a feeler gauge, between the shoes and the surface of the gauge. On my GC, it took two "clicks" of the adjuster on the LH side of the vehicle, and 8 "clicks" on the RH side.

Although this greatly improved the holding power of the brake, I think I should have set the shoes a little closer, as I can still somewhat overpower the brake by applying the gas, but it IS considerably better than it was before. If I get some time in the next couple of days, I'll get back in there, and give the adjusters another 2 "clicks".

I'll add this.....trying to use the "access slots" would most likely be an exercise in futility. It would be easier to just pull the calipers, caliper brackets, and rotors.

One more thing....

For those "adventurous souls" who'd like to try the adjustment without removing the calipers/rotors, the mysterious access slots are located at the "2 o'clock" position on the LH side, and the "10 o'clock" position on the RH side........Good Luck!!

I totally agree, and if you live in the rust belt, you will need to get the corrosion off the parts anyway if it's a few years old, imho.

Those positions you describe are from under the jeep in the back of the brake correct? Or is that with the wheel off looking at the brake?
