I had earlier posted asking about how long the steel brake lines last. I had decided to replace hoses, but not the lines. But I can't loosen a couple of fittings so I'm going to have to change the lines on the rear axle, too.

I think the "old" lines are the original, I'm the 2nd owner. On the driver side, the steel line runs from the center distribution block of the hose all the way to the caliper (4-wheel discs). On the passenger side, the line runs to a hose, and then the hose to the caliper.

I ordered pre-bent replacement SS lines from Inline in MI. The lines that I got both run from the center to the caliper. The passenger side does not go to a hose.

I made sure Inline knew it is an '83. The fittings are "inch", so they screw into the new hose block (they're not '84, when things changed to metric).

Did GM sometimes change things during a model year?
The car was built in Van Nuys, did they do things different at different ass'y plants?
Does Inline have bad info on '83's?
Does anyone else have an '83 TA with 4-wheel discs? How is the passenger side put together?

Thanks
 
strange that there is a difference. You need a copy of the factory manual for the car and make sure Inline knows it's for a 4-wheel disc brake setup. If you remove the hose on the passenger side will the line they sent you fit?
 
I have the GM F-body manual for '83's. The drawing for the rear discs show a brake line like what was sent, but it says "typical". I am assuming they mean it is representative, or a general drawing. That's why I was wondering if things change mid-year.

Anyway, I cut the tube to fit with the passenger side hose. There is a factory bracket where the hose and tube connect. I would have had to do a lot of re-bending to "delete" the hose. The attached shows before I made the connection.
 
then i would say Inline may have sent the wrong pipe, did you get back to them about your problem?

I sent them an email with an picture showing how it didn't fit. It was more of a "did you know this?", not a "what's wrong with you morons!". I haven't heard anything. ???
