Look into the intake side of the carb it will be in the lower part of the opening. when you say brake pump do you mean the caliper (at the disc) or master cylinder (at the foot pedal)? Hope this helps get you running again. Quote

patsbansh Posted June 20, 2011 Report Posted June 20, 2011 master cylinder when i got my first banshee i bought a clymer manual they cost about $20 it will be the best 20 you ever spend. If you are looking to rebuild it there are many places that sell these rebuild kits, has it ever worked? sometimes bleeding them can be a bear. If it has no fluid leaking out when you detatch the line from the caliper, i use an eye drop bottle to force the fluid through to begin the bleeding process. there is a rubber boot on the bottom of the master and a snap ring that holds everything in place, once that is removed the whole assembly slides out. check the plunger on the inside for dry rot and rust. make sure the spring is good and the inside of the cylinder is clean.

Good luck with it hope this helped Quote
