Do rubber brake lines have to be a special length ?

Originally those were not rubber but a blue woven fabric with some sort of liner. If you use rubber, make sure it is rated for brake fluid or else it will swell up and fail.

With that said, the length should not matter as long as it is positioned well above the master cylinders because gravity feeds the fluid down to the brake and clutch masters.

You can sort of see the blue stuff in this picture. It is available from the usual BMW part sources.

The guy I got the lines from races a 2002, and has it on his car, so I hope its the right lines...

I am converting from 2 reservoirs (one clutch, one brake) to the more modern one that has one reservoir. My problem is I dont have that "piece" next to the strut that holds it in place. That leaves me to bolt it to the firewall.

Is it safe for me to do that ? (I will keep the reservoir higher than master cylinder)

The ones that run from the reservoir to the master cylinder. I want to connect the reservoir to the firewall. If you can see closely there is a small hole I wanna use...

Is it safe to shorten the hoses and connect it to the firewall ???

Another option is to use the brake fluid reservoir and bracket from a boosted Porsche 911. The bracket bolts perfectly to the top 2 bolts of the 2002's brake booster, although you may need to radius the bottom of the bracket to clear the square portion of the 2002 booster bracket (it's all ATE brand stuff that the Germans used to use). You'd need to lengthen your brake fluid feed lines and/or replace your master cyl fluid feed nipples with vertical ones (available through Pelican Parts and many other suppliers). I used a single feed, round brake fluid res from an early (66-68?) 911/912 for the clutch master cyl and fabbed my own bracket to hold it right behind the 911 brake fluid res on the 2002 booster.

It looks clean, I'll post some pics if you're interested.

Sexy!

Yes, it's okay to bolt the reservoir to the firewall or inner fender.

In the picture, is the fluid suppose to be at the levels shown? My fluid levels in my 1974 Tii are below the, is it the clutch line, line coming out the side of the reservoir. If I fill the reservoir above the clutch line, do I need to bleed the clutch line? Is there going to be air bubbles in clutch system...does it matter?

no fill it up. as long as your clutch is currently working as it should youll be fine. The bubbles escape themselves
