Anyone ever changed hard brake lines on their E30?

Seems like mine are rusting badly and need to be changed to even be able to detach the softlines to change them for SS ones.

How much work is it to change hardlines?

Thanks
Alex

I did all the rear hard lines on my old 325e and it was a royal pain in the ass.

New hard lines come straight so you need to bend them to the correct shape. That's not really the hardest part though. The T-junction where the lines meet is a real bitch to get to.

I'd recomend if you are going to tackle this that you get new lines, new T-junction and new plastic line clips plus the spring clips that keep the fittings from moving.

Let me know if you have any questions when you are doing it.

^^ hey thanks a lot bud

my mechanic recommended to go with "prebent and ready to go" ones from dealer.
How much did you end up spending for parts?

Also please tell me what exactly has to be removed from the car to do the full rear hardlines.

Thanks
Alex

I'm afraid there is no such thing. Lines from the dealer come straight and need to be bent.

Rigid Lines

T-Junction (splits line from front to rear) - 34 33 1 163 566 - $16.00
Pressure Regulator to T-Junction (NON ABS) - 34 32 6 755 686 - $26.00
T-Junction to passenger hose under subframe - 34 32 6 755 567 - $12.00
T-Junction to drivers hose under subframe - 34 32 6 755 557 - $8.79
Passenger subframe hose to caliper hose - 34 32 6 755 590 - $12.00
Driver subframe hose to caliper hose - 34 32 6 755 590 - $12.00

Total $86.79 cdn

These were from the dealer and it was about 4 years ago. This was for a 85 325e without ABS so you'd need a different line from the front of the car for an ABS car.

At a minimum you need to remove the wheels and jack the rear up high. If I attempted this again I'd combine it with a subframe bushing job and drop the whole rear. Would save bags of time mesing around with hard to reach corroded parts.

Note that even with the subframe off the car, it can still be a pain in the ass. Be sure to use lots of penetrating oil and heat to get the fittings to turn where you want to keep your old lines. Be especially careful at the master cylinder, etc, where your reach is limited because if you bork a fitting or some threads there, you are looking at some SERIOUS time to remove everything to get at it.

Some big jobs are satisfying. This is not one of them.

Be very wary of using heat on brake fittings, you can pop the rubber line fitting.

For me it was the fitting at the proportioning valve under the master cylinder. Really tight area and a pain in the ass.
