Hi,

I have a 1988 IROC with a G92 package, 9 bolt posi rear end and factory rear disks. These are the Delco disks where one caliper is mounted front and the other rear.

I bought a Goodridge 12252 SS Braided Brake Line kit and have a fitment problem.

The Goodridge kit has four hoses - a pair of matching hoses for the front and a pair of matching hoses for the rear.

The front and right rear flexible hoses were replaced fine.

The problem is that the line going into the left rear disk caliper is a hard line that runs directly to a T junction that supplies fluid to the rear brakes.

That is, there is no need for a flexible hose on the left.

However, there is a flexible hose in the rear centre that goes from the body to T junction to feed both the rear disks. This is needs for the flex as the body and rear axle have different travel.

The left over Goodridge hose has a female thread, but is too small for the make thread for the fluid that comes from the front of the car.

I assume the centre line carries twice as much fluid, so is bigger than the fitting that goes into individual disks. That is, one rear hose should be bigger than the other.

The Goodridge rear hoses appear to be a matching pair so don't fit the centre hose.

Also, one end of the spare Goodridge hose has a ring for a hollow banjo bolt (?) when I suspect it should just have a male thread to just screw into the T junction that distributes fluid to the rear.

Any suggestions?

looks to me to be a screw up. I would give them a call and ask about this.

I've contacted Goodridge and have got a reply.

I think they get confused by the "Performance Package", which I think means 1LE.

This problem only relates to the rear-end, and all disk rear-ends were the same in 1988 as far as I can tell.

I'm thinking of upgrading to the PBR rear disks and calipers anyway and trying to find the difference is fluid plumbing too.

Got to way the quality and finish of the Goodridge brake lines is impressive.

The early J65 set-up should have four lines: left and right front, one to the pass side caliper and one from junction to body. The late J65 set-up (89-92) (1LE or perf package) should have five lines: left and right front, left and right rear, and one from the junction to body.

@JamesC, thanks for the reply. Thought I'd missed something.

The Goodridge kit #12252 is supposed to be for 1984 to 1988 disk rears and have five lines, which is wrong. The kit for this year should have four lines like you said.

The Goodridge kit #12254 should be for 1989 to 92 disk rear Camaros and have five lines.

I think they have just screwed up the packaging. Goodridge customer support seem pretty good so hopefully I can just get them to send me the missing hose.

Bit of a pain because the missing hose is to replace a broken hose which snapped off inside the T junction :-(

I have that 12252 kit and it has 5 lines. Clearly you are missing the body to differential. Obviously you only use 4 of the 5 since the left rear is a hard line.

peterc005

My mistake, found the missing fifth line in the bottom of another box :-|

I'm impressed with the quality of the Goodridge lines and think the brass T junction is much better than the factory part.

I still have a spare rear hose, as there is no flexible hose going into the rear left caliper, just a hard line. Am I missing something or is this really an extra hose?

I want to upgrade to the PBR brakes and this makes it easier. I suspect the 12252 and later 12254 kits are the same>

Nice. Glad to hear. Goodridge makes nice stuff. Your remaining hose is extra, no need for it on these cars.

One question for you. I bought my kit about 2 years ago and the stainless braid was uncoated. I picked up a Goodridge kit for my daily driver Acura CL this week and the stainless braid has a clear cover over it. The cover is a nice feature to keep crud out of the braid and to protect everything else from the braid. Do your lines have the cover?

peterc005

No cover on my braid and I bought the kit about six months ago.

You've got to wonder about the claims of braking performance of the stainless steel braided kits, but the quality and finish are certainly impressive.

My plans are LS1 disks on the front and later model PBR disks on the rear and it looks like I'll be able to keep the flexible brake lines.

I am tearing out my hair about brake lines! i really don't understand what kit I would ever need, as no one has pictures of the actual kit they're selling.

The early J65 set-up (your 87 is included) should have four lines: left and right front, one to the pass side caliper and one from junction to body. Most pics are representative only. Don't rely on them.

Thanks for clearing up the confusion. I really couldn't remember that there was a hose on my passenger side rear.
