Brake Pads - BMW R850 Maintenance Manual

3. One Man Brake Bleeder is a one way valve that attaches to your stock
bleeder nipple via a hose. It is available at some auto parts stores.
4. A turkey baster is handy for removing the old fluid from the reservoir
before you add the fresh fluid. Once you use it for brake fluid, do not
return it to the kitchen.
Note: If bleeding by the standard method of pumping the lever, do not pull the
lever all the way to the handlebar or you will force the caliper piston too far out
and possibly ruin the seal. This applies to the clutch and rear brake as well.
Note: On the 1150 GS, BMW has a plug or grub screw instead of a bleeder
nipple on the right front brake caliper and on the clutch slave cylinder. BMW
wants you to replace these with a bleeder nipple to bleed the system and to then
reinstall the grub screw when you are finished.
Note: For brake bleeding procedures see

Note: Check front and rear pads for wear and replace them if they have less than
1 mm of pad left. Remove the right saddle bag so you can do a good inspection
of the rear pads. See the section on brake pad replacement.
Warning: Due to a sticky rear brake retaining pin, the rear pads can wear out in
only a few thousand miles. Clean the pin with fine emery paper and lube it with
anti-seize. See the section on brake pad replacement.
Note: If either the front or rear brake fluid reservoir is low on fluid, be sure to
check the brake pads for wear! As the pads wear, more fluid is taken into the
system.
Note: Be sure to check the brake fluid reservoir after replacing the pads as fluid
is forced back into the reservoir by the new thicker pads – the reservoir may be
too full.
