Long brake line replacement

[christofult]

Hi,

I have a leak in one of the brake lines that travel towards the rear brakes. I can't find any information for how to do this replacement, but I've already replaced the rear lines. Could someone tell me the legnth of the line I need as well as where to disconnect/connect them to?

Any help is appreciated.

1989 735IL

Thanks!

some info is here in section 34-32 https://www.bmwtechinfo.com/repair/main/Index_cd3.htm
Instead of steel use Cunifer copper nickel, much easier to bend. You will be able to bend it by hand , source for example http://www.brakeconnect.com/product/...kel-brake-line

Even from BMW you do not get the lines pre-bent, just a coil by meters.

Is it worth a call to BMW to figure out the legnth of line needed to avoid screwing around? I have a 30 inch line but its not nearly long enough as the line running from the front to rear meanders a little.

better measure by yourselves, there are not many people in the parts sections of BMW shops which know the E32 better than us, maybe they were just born when the E32 came into the market.
