Jag XKE Emergency Brake Question

Jim Coleman · #1 (**permalink**) 05-27-2019, 02:38 PM

Looking at the emergency brake assembly, I noticed that it operates by squeezing two levers together, one pulls the right pad, one pulls the left side.

My question is, how do I get the levers to pull equally with one cable ?

Thanks,

Jim

We make a pass-through bracket that connects the cable housing to one side and the cable end to the other. Since the cable must enter crosswise, it must take a quick 90d to head forward to the emergency brake handle.

Sounds good, do you have a photo of the bracket and a drawing or photo that shows the installation? Also, do you carry the cable ?

Please send me a PM on how to order the parts.

Thanks,

Jim

I'm not very familiar with that caliper but in general on Girlings, the lever that attaches to the cable pushes one arm while pulling the other. There's a threaded rod between the inner and outer lever that pulls the outer arm in.
If that makes sense!

Oh wait, you mean one cable and two calipers! Got it now!
I thought you meant how does the outer pad get pulled into the rotor.

Yeah, it's a little complicated with 2 calipers and 1 cable.

Thanks,

Why couldn't you use two cables that attach to the brake handle? Like a Lokar setup?

Larry,

First off, I don't have any cables yet - plus one cable has to push and the other pull.

strictlypersonl says they have the part that will make one cable push and pull as original.

Thanks !

Jim, what Larry suggested.

Here's what I did....

Cheers,

Wow!

Beautiful weld work on the aluminum.

Thanks for the tip.

Well, that's what this forum's for

Here's what the cables look like at the other end....

You can see where the two cables come through the bulkhead just to the right of the diff.

Cheers!

Well you can’t push with a cable, it can only pull. Like I was saying in my first post, Girling parking brakes work by pulling the cable lever on each caliper. When the lever is pulled, it pushed one pad and pulls the other on each caliper. It’s similar to Girlings on original Cobras. I’ll see if I can find a photo. It’ll make it easier to see.

Look through this thread and you'll find a couple interesting photo's showing the cable routing on a Jag rear end. Might given you some ideas.

Thanks, Larry

The photos do give me some ideas.

Thanks again, everyone

A friend offered me the original XKE cable and parts to complete my E brake.

If it's only used as a parking brake, what difference does in make if they pull evenly? As long as one side engages and stops the car from rolling, it will work fine. Won't it?

Jim Coleman · #17 (**permalink**) 06-02-2019, 04:06 PM

Dan,

I'm not sure if one side working is enough to stop the car from rolling, I have pinion mounted parking brakes with one caliper on a couple cars and they don't hold too well.

Thanks,

Jim

I went through this last year, and it was quite painful. I use a single cable that pulls both parking brake levers towards the center of the differential, and it works very well. I use a Fiat 127 parking brake lever with a single cable. The key to getting the Jag parking brake working is adjusting the ratchet mechanism. I fiddled with a nonfunctional parking brake for months, until I read a great article on fixing each caliper's ratchet mechanism. The cable passes through the RH lever and terminates on the left.

I have the same problem. Left side adjusted up fine, the right side adjustment screw doesn't tighten (just turns like a stripped thread).
One side will keep the car from rolling in my driveway (less than 5 deg. incline) but would be useless if the regular brakes fail. I wouldn't trust it the way it is even on an incline greater than my driveway.

I have about 3 sets of arms if you need some pieces.
