parking brake not holding

just wondering if you guys can give me some other pointers on what else to check. i have a 99 TJ sport. the rear has been swapped to a D44 with rear disc brakes by the previous owner. a VIN breakdown shows that it originally came with drum brakes on the rear.

i had the parking brake shoes checked & verified that they are still in good condition (thickness). but when i pulled up on the handle, it wouldn't hold the jeep at all. i had the parking brake adjusted twice by 2 different techs at 2 different shops. it definitely made things better, but it still is not holding the jeep.

not sure else what to check or have checked. one of the techs said it could be that the parking brake cables are bad. how can i verify that? there is tension when i pull up on the handle. it definitely kinda holds the jeep, but it still drifts.

Welcome to the world of Jeep; leave it in gear/park when you shut it down. Mine won't hold on flat ground against a stiff breeze.

Something is wrong. I can set my e brake and it'll hold on an incline. Not crazy steep but a decent incline.

Are you having an issue with it rolling in reverse or forward? It is pretty normal for it to be weaker holding it feom going backwards. You should however be able to adjust it to keep it on any kind of decline. Mine stops at 4 clicks and keeps it after adjusting it properly.

I have the same problem and was told that it might be a problem with the shoe friction material of aftermarket shoes. I haven't switched to oem shoes yet so I don't know if this will solve the problem or not. I was also told it could be worn out cables that were stretching but I tried tightening the brakes to the point where I could only pull the handle half way up before it was tight and the jeep still rolled.

i haven't honestly checked to see if it rolls backwards since i usually back into the driveway. i'll have to check that.

mine is adjusted the same. i might get 4/5 clicks before i can't pull it up higher, but it still drifts forward.

The brake should only click 2 or 3 times.

Pop the rubber dust cover on the back drum and adjust the star wheel. Take the rest of the slack out of the cable and done. I'm sure if you search there is a more detailed description.

I know years ago Jeep had a recall on the emergency brake mechanism. I had a 95 that was replaced in 2006 under recall. May still be in effect. Look up recalls for your year

To properly set a parking brake you must apply the primary brakes; then set your parking brake. The applies to all vehicles.

I'm not sure how this would do anything different when the rear drum/shoe e-brake is a totally separate system from the rear disc/pad service brakes. Either way, I've tried it and it has no effect.

I have tightened the adjustment mechanism (star wheel) inside the drum until I couldn't even spin the tire by hand with the e-brake handle down while on a jack. Then lowered the jack, applied the e-brake and the jeep still rolled on a slight incline.

I think you need to remove the drums and see what it going on inside. These things become gunky inside and the springs, etc don't work like they should anymore. Get some brake cleaner, open them up and clean them up. This way you willl also see if the shoes are not contacting properly.

every bit of hardware in the rear is brand new including rotor and shoes. I have the caliper reversal setup from Black Magic and have verified through him that everything is installed properly. Blaine in fact is the one who suggested I tried OEM shoes since he had the same problem on one of his vehicles and found it was a problem with the friction material on the Centric shoes. I will know for sure once the weather warms up a bit and I get a chance to pull the brakes apart again.
