Hi,

Pretty much have my 1le rear brake upgrade almost done. This board has been a huge help. I do have one question about the emergency brake though.

I ran the cables back to the stock location but they go past the piece in the tunnel that they are supposed to connect to. Even if I put the piece to its limit the cables are still too long by 3-4 inches. Any advice?

 

What year is the car? What year is the doner axle/brakes from?

I might be able to help you.

Thanx,andyZ28

 

Is the brake upgrade on your '87 or the '92? Does your e-brake adjuster look like this??

 

car is an 87 brakes are from a 92!

 

axle is 9 bolt borg warner. i swapped on new backing plates for the brakes to fit, so only the brakes and backing plates are donor equipment.

You have the wrong parking brake cables. You will need the ones for an '89 with J65.

Thanx,andyZ28

 

Andy,

Is there a P/N on these? Will the work with the existing equalizer? I may be stupid here but I pulled the brakes with e-brake cables off of the 92 z28 1le. what is the difference in the cables? do i have to have J65 specific to 1989?

Will one from 91 work? I found the P/N for 91 E-brake cable with J65.

Does the equalizer need to be replaced as well?

Sorry for the confusion in questions just wanna make sure i get the right parts

 

i too did the pbr swap on my 88'. if you want you can go to orieleys and get the e-brake cables from them. they were the wagner brand and have worked ok for me. if you want oem then might try a search or someone can post part #'s for you.

 

I believe you will need 2 of part# 18033788. The parking brake cable saga is a long story. So I won't tell it now. But I believe these are the cables you need.

Thanx, andyZ28

 

thanks andy..

the other issue i ran into was at the proportioning valve and getting the lines to screw in.. No go.. Are these differerent as well.. I was searching around.

The valve and MC i got is from a 92. Are they m1.5 as opposed to M1.0 threads which I think are on my car?

 

Your brake lines on the 87 are SAE and the 92 are metric.

 

Umm.. I thought they were all metric after 1984.

 

Not when I installed a 1989 9-bolt in my 1987 IROC. The lines are different.

 

You will need the proprotining valve from an early '89 J-65 car. If you get a new one ( highly recommended) from GM your lines should fit.

Thanx,andyZ28

 

Yep, '84 and later all have the ISO metric "bubble flare".

 

Zimms, you will need to install prop valve # 14089496 since you have an '87 car. AndyZ28 has more info and so does Daniel Burke.
