Jalpa Parking Brake Cable
Before I turn Chad loose on looking for one
 My parking brake cable snapped today when I went to pull up on the handle. Any Jalpa owners out there have an extra they want to sell? GT Car Parts is out of stock, Jacques is also out. I have a call into George Evans too.

Mike,
it sounds like you're covering all the bases :-) Chad should be able to find it!! He's good w/ the e-brakes - and has been very helpful to me. George Evans used to have one set ... If you're in a pinch while you're waiting for the 'real' cable you might want to take a look at yours. I know on my Urraco I've had problems w/ the cable set GTCP sold me. It's 1/8" diameter (if memory serves) braided steel cable w/ some brass plugs soldered on the end to hold it at the center e-brake handle and some cable stops to hold it at the e-brake arms. As you can imagine, the soldered brass plugs at the e-brake handle end don't hold real well. If what snapped were the stops/plugs at either end, in a pinch you can: > Go to your local HW store, get a say 1/4" threaded hex join (they have to let you join the threaded metal dowels they sell) - choose the join to approximately match the size of the plug/cable stop you're trying to replace > Drill a hole through the join for your cable, > Thread the cable just through, > Run a screw through the join thread to 'clamp' the cable - use locktight to make sure the screw doesn't back out. You should be good to go for a while w/ this arrangement while you wait for the 'real' cable. If the cable truly snapped, again if you're in a pinch a motorcycle shop (or your HW store) should have a replacement you can use w/ the approximate right diameter. You should be able to thread the new cable through the sheath and other HW from the old ... haven't done that though as my car 'arrived' totally devoid of the original HW. I'm sure others more mechanically inclined will have suggestions. You could also get steel dowel stock (again from the HW store), drill it as above and then weld it to the cable (all instead of trying to re-solder the brass plugs), but IMO the join and screw method is simpler to execute and should work well (although I admit I don't have a lot of time on it yet :-).

A couple folks had asked me if I would take some measurements of the cable once I got it out. Turns out the cable was broke inside the sheathing about 1/2 way up the passenger side.
But here are the measurements for those folks that wanted to know: Wire Diameter: 3.0mm Lead Piece that is "swaged" on the end of the wire: 7.6mm OD Brass Barrel that attaches at the caliper: 10.0mm Diameter x 17.6mm wide x 7.9mm hole (where the lead piece recesses in) I'm not sure what the total length of the wire is, since mine was pretty frayed where it broke. But, I can measure the new one, once it gets here.

Hey Mike
I found this countach brake cable on ebay. I'm not sure if it will work with the Jalpa, but someone can chime in and verify. The link is below. http://cgi.ebay.com/ebaymotors/LAMBO...88577956QQrdZ1

Thanks Terry. That is George Evans selling that Countach brake cable. They are different than the Jalpa, and he was sold out too.
But, I did find one! Woo-hoo! It should be here next week.

Hi Mike!!
Glad you found a replacement!! Hate to say it, but you might want to check the other side as well for wear, etc :-) Nice pics btw!! Pieces and sizes seem to match my Urraco FWIW. Best regards, Bryan '74 P250S S/N 15622 Indianapolis Indiana USA blissinindy@yahoo.com

The Jalpa Brake cable is a one piece unit. Not 2 pieces like the Urraco.

Mike,
thanks for the update and the illustration!! I (obviously) wasn't aware that the cable was one piece. This newer arrangement seems an improvement e-brake balance wise. As long as you're educating me, two questions if you wouldn't mind :-) Can you briefly summarize installation - what do you have to remove/thread? Where are the springs on the brake 'arm' end of the cable positioned ... to the rear of the 'arm' ? Thanks!! Bryan '74 P250S S/N 15622 Indianapolis Indiana USA blissinindy@yahoo.com

I'll take a photo of it once its installed. The installation is pretty easy.
My hunt continues for a brake cable however, the one I got was for a Countach, which is about 1 foot short on each side!
