8.8 Parking Brake Cables

97 TJ 4.0 AX-15.

Recently swapped in a 8.8, which works great, except for the Parking brake. I ordered the Cables from ECGS and the brake still doesnt grab. Parking brake shoes are in good shape, the cables are just too long. I tried tightening then with luck. Called ECGS and they said the 8.8 cables just dont hold well (seems like BS to me).

Has anyone else had this issue? How did you resolve?

Thanks

Yeah the 8.8 cables are known for sucking. I tried new shoes for it and tightening it to the max with the adjuster on the tub and neither helped really.

Has anyone tried the Black Magic reverse bracket kit? How much does it help?

I have it sitting in my garage, just debating the amount of work needed to install it.

Have you adjusted the brake side yet?

For some reason by parking brake works wonderfully at keeping me from rolling backwards, but not at all forwards.

I adjusted both ends and cant get it to hold. I even had my mechanic look at it and he said the cables were too long.

Blains black magic cables do make the parking brake hold a lot better, but I did have to grind down the tabs of the cables to fit into the round piece of the adapters. Not a big deal, just kind of tricky. I'm happy with the end result as the ebrake holds better and the calipers are flipped forward for outboarding shocks. BTW I used 2006 wrangler parking brake cables from NAPA

If the cables are too long relative to the cable housing it is because they are using ZJ parking brake cables because they are cheaper.

Properly adjusted, the parking brake handles sets hard about 3 clicks up from the bottom.

Adjust the shoes at the drums first with the tire off the ground until there is some resistance turning the tire by hand. Go for a short drive slowly and lift and lower the brake handle a few times to apply some brake while rolling to bed the shoes into the shape of the inner drum wall.

Go back and re-adjust the shoes again to the same slight resistance and then adjust the cables at the splitter snug but not tight enough to move the levers.

If the cables won't tighten correctly, remove the nut and add a considerable stack of washers onto the threaded part to take up some space so they can be adjusted correctly.

We did that for years until the Rubicon came out and we could buy the right cables.

I have a similar problem. I also have a 8.8 from ECGS. Mine has disc brakes though. What cables can I use to correct this ? I have my adjuster tightened as far as I can and not even close to working.

Which cables do you now use and where do you source them? Ill try your steps but would like a back up option if needed.

Thanks.

I have OEM TJ rear disc parking brake cables NIB sitting at the house. If no one posts them I can look and post the PNs when I get home tonight.

My RHD TJ - Savvy equipped... And loving it!

I drive on the right side, what's wrong with you?

I only use OEM at this point and will until they no longer make them. I get them from the dealer.

But, that very likely isn't your problem if you apply the fix to the adjuster. It isn't that the cable is too long, it is just too long for the length of the cable housing.

When I did my rear disc conversion last year with the Grand Cherokee hardware I found the new stock GC cables were to long also, so I removed the spacer from the adjuster assembly under the tub and picked up several inches. I removed the part that looks like a bent nail and the coulping.

That's what I had to do too

I've got an ECGS 8.8, with discs, and after adjusting the brake shoes, I was able to take up enough slack to get the e-brakes to lock down on about the 4th click. I used the cables I ordered with the axle. I haven't had any issues with them being too long, or not staying where they belong.

You don't have to remove anything permanently. Just add some washers or do like I used to and cut a piece of tube about an inch long, remove the nut, slide the spacer over the threaded section and put the nut back on.
