#279755 davidcoons (User) Fresh Boarder Posts: 14 Rear Brake fluid leakage 2 Years ago   Hi, I just installed an aftermarket rear brake master cylinder on my 01 RoastStar and after bleeding the brakes I seem to be getting some oil leakage from inside of the brake caliper up and back behind the bleed screw. Any ideas?   Logged     The administrator has disabled public write access. #279770 Curt (Moderator) Never to old to ride!

After trying to bleed and tighting it all up, when steping on the brake there seems to be small amount coming out from behind. I leave a small tissue on top of the pads stuck into the gap between the housing and it picks up a small amount of oil. No oil from the seat of the screw on the housing, just comes from inside. A bit frustrating but I think I'm leaning towards leakage from the pistons I guess.   Logged     The administrator has disabled public write access. #279787 Curt (Moderator) Never to old to ride!

All the bleed screws I have seen are just one piece like a car has.   Logged     My Site Black Ice is Shiny, Black Ice is Deadly, Ya Wanna Ride My BlackIce?   The administrator has disabled public write access. #279815 CPORetired (User) What do you mean my birth certificate expired?!!!?

David if this is the case you way want to look into getting the old standard bleeder valve, it may save you the headache, just a thought guys.   Logged     Any man who may be asked in this century what he did to make his life worthwhile, I think can respond with a good deal of pride and satisfaction: I SERVED IN THE UNITED STATES NAVY.

I do have the full shop book and it looks the same as in the repair manual. I even ordered a new bleed screw but it was not the same as on the brake. I have attached a few pictures. 1 is of the brake and 1 is of the bleed screw set and the leakage is where you see where the paper is stuffed at. It seeps when I apply the brakes just slightly.   Logged     Last Edit: 2010/05/06 00:39 By davidcoons.   The administrator has disabled public write access. #279873 davidcoons (User) Fresh Boarder Posts: 14 Re:Rear Brake fluid leakage 2 Years ago   here are the pictures.
