Question:

how to bleed brakes after changing master cylinder on a 20052 harley sportster?

im changing the fluid in my rear brake system on my 2005 harley sportster. how do i get the fluid back to my rear caliper

Answer:

I like to use vacuum bleeders to get the air out of the brake system, and the fresh fluid down to the caliper or wheel cylinder. You can rent vacuum pumps/bleeders at any local autozone if you dont personally own one. Its faster than gravity bleeding, so it will get you back on your Harley faster. The 2005 XL's use a DOT4 brake fluid, so make sure you dont get any of it on your paint or it will eat it pretty quickly.

All they are doing is getting all the air out. A master cylinder is nothing more than a syringe like the ones used in the hospitals and even there the doctor pushes out the air before injecting the person. You don't really need a bench job. Most vehicle braking systems are designed to self de-aerate. You can also open each one of the bleed plugs located at each one of the brake cylinders and bleed them one at a time. The only difference is that the shops will try to recover the liquid which can get to be expensive.

fill the reservoir , Connect the bleed valve to a tube submerged in fluid .undo the nut, pump the lever do up the nut ,continue until all the air comes out do . this may take some time ! i hope you have some patients
