Hey Genltemen,

When you view the schematic for ( Brake Line,Integral ABS,Front ) on Max Bmw for an '02 LTC, is that front brake line worth trying to tackle myself ? I do realize that I will need to bleed the system, and I also have the facrory service manual and the Clymer for my machine. Oh, I should add that I am mechanicaly capable, I own a BMW.

Go for it, it is very straight forward. The OEM front line comes with both pieces as one part #. Some folks go for the Speigler brake lines which seem to hold up better. Also, it is best to replace all of them at the same time mho.

Seriously, is bleeding the system that complicated ? I don't know.

HERE is one thread with short description.

If you are just replacing that one line try to keep fluid loss to a minimum. Then make sure you have the rear (back half) of the rear reservoir full (#1). Connect a long piece of clear tubing to the closest caliper to the line youreplaced) and run it back to that same reservoir. Open the bleed nipple on the caliper and turn on the key and let the ABS pump move the fluid. Pump until there are no air bubbles in the line. Keep a close eye on the reservoir and don't let it go empty. Once the air is gone close the nipple and remove the tubing. Top off the reservoir and enjoy.

OK I re-read your post and I am not real clear on which hose you are talking about. If it is any hose other than #1 this post will help. If it is hose #1 I need to give ayou a different procedure.

Tomorrow when I get home from work, I'm going to pull the fuel tank and radio box so that I can see for sure which hose it is. I'll let you know then exactly what is leaking. Thank you

So John, It is the number 1 hose. Wouldn't you have to bleed the entire front system anyway. Everytime you squeeze the brake lever, it swirts fluid, only to suck in air on the return path. Tom

OK then forget what I posted earlier.

This is all within the front control circuit so you would have to just bleed from the reservoir down to the ABS pump unit. Open the reservoir up and suck all the fluid out of it before you remove the old hose. Then install the new hose but leave the reservoir empty. Get a large syringe ( I get mine at a local Tractor Supply) and some tubing and push fluid from the long bleed nipple (#4) on the outboard side of the ABS unit up to the reservoir. If you are careful and make sure the tubing is full of fluid when you put it on the bleed nipple you should be done when you fill the reservoir with the syringe.

Another way would be to use the filler port shown in #1. You need to have an M10 short bleed nipple to insert once you remove the grub screw but this method eliminates any air getting into the ABS as this is between the reservoir and the ABS unit. Might be a better way to do it.

And then my last question, and I just can't find the answer. How do I loosen the right grip so that I can twist is slightly to be able to get to the bolt on the brake line ?

You need to remove the big black screw on the contol face, the tiny silver screw on the back side in the mirror hole and the silver screw under neath the controls. Then you can pull all that away and get to the 4 mm allen on the master cylinder.

John, thank you for your help. I tried getting a hose made local,but not happening. It was the crazy fixture on the end that is bolted into the hardline that stopped production. Anyway,MAX BMW has my order and I'll have the part in a couple of days. I'm taking advantage of having everything taken down and changing the air filter, and just checking everything over. Gotta make this a positive. Thanks again. Peace
