The parts list is updated as of 8/7/2007
I'm including some pictures of this procedure, but the actual credit for the procedure must go to Freek who pioneered this bit of cosmetic surgery. Thanks Freek.
The procedure is quite simple:
Tools needed:
T10 Torx Screwdriver (one on the end of 1/4/ ratchet and extension works well)
This is to remove the small torx screws that hold the canister to the fitting on the brake lever)
4mm hex wrench (this is to remove the screws from the top of mounting bracket)
T25 Torx screwdriver (this is to replace the new screws that hold the top of the brake handle to the handle bar)
Needle nose pliers (this is to remove the small clamp that holds the fluid tube to the top of the fluid fitting)
Supplies Needed:
Towel to catch any droplets of brake fluid (DO NOT LET IT TOUCH ANYTHING PAINTED!!!)
New Can of DOT 4 brake fluid
Parts Needed: (I obtained all from Hammersley Motors in Lynchburg VA -- total cost $55.05 including shipping)
New BMW Fluid Reservoir 34-31-7-658-914
2 plastic screws 32-72-7-675-118 (in spite of the name, they are metal, but they are specifically for screwing into plastic)
2 M5X20 Torx Screws 07 12 9 904 792 to replace the 50mm screws that hold the original bracket to the handle bar (don't forget these, the original screws will be way too long without the bracket)
1 "O" ring 32-72-7-675-117 (this is a new ring for the reservoir. It is probably not needed since all of the original rings are still very new)
the procedure:
1. Remove the reservoir from the bracket using a T25 screwdriver)
2. Remove the 4mm hex bolts from the bracket and remove the bracket
3. Replace the 4mm hex bolts with the T25 torx screws mentioned above (it is important to do this first since you will not want to be moving the brake lever after the reservoir is removed)
4. Clamp off the rubber hose that goes from the reservoir to the fitting on top of the lever (I used a hemostat)
5. Remove the hose from the fitting on the top of the brake lever by loosening the clamp with needle nose pliers then push it off the fitting. Remove the old reservoir and set it aside away from any painted surface (its till full of fluid at this point)
6. Remove the small T10 torx screws from the bottom of the reservoir (I can't describe how to do this, its awkward, but persevere -- they are not tight -- use Irish cuss words)
7. Remove the fitting from the top of the brake lever and cylinder and set it aside away from any painted surface.
8. Check to be sure the the "O" ring is still in place on the brake lever/cylinder (be sure its in good shape -- it probably is since it can't be more than 2 years old at the oldest)
9. Fit the new reservoir to the top of the brake lever and replace the T10 Torx screws that hold it on.
10. Fill the reservoir with new DOT Spec 4 brake fluid and replace the cap tightly.
11. Stand back and admire your work.
12. Dispose of the fluid in the old reservoir in accordance with your conscience (don't poor it in the drain please).
Put all of the old parts in a plastic zip lock bag and hold on to them forever just in case there really was a good reason for the cheap looking bracket and hose arrangement.
