proper BBK installtion?

[logicmobile]

we tried to slp on a bbk on my G 03 sedan but when we are in Bleeding part , instead of the fluid squirting out from the bleeder screw, its just a dripping, so we end up putting back the oem and easy as 123 when bleeding back....thank you

Yes.

basically when we are trying to bleed the BBK , it wont hold pressure , the pedal goes all the way thru...why is that happen?

First, is there fluid leaking out somewhere other than the bleed valve when you pump the pedal? If yes, then you trace the leak and figure it out. Brake fluid leaks are bad, bad news. If you have a cross-threaded fitting or a leak, don't mess around. Replace it.

I assume you know how to bleed brakes, but to be sure, you should be:Opening the valve at the caliper, THEN someone pushes down the brake pedal, THEN you close the valve, THEN the brake pedal is released,THEN start over.

If there are no leaks, then I'd make sure the system was all together with brake pads and rotors in place. This gives the pistons something to press on.

If you've done that and it's still soft, then all I can say is make sure to keep the fluid reservoir full and keep bleeding because there must be air in the system somewhere. If you got some air in near the reservoir, then it could take a long time to push it through.

One last option. The caliper could be bolted on upside down. The bleed valve needs to be at the TOP of the caliper. If it is at the bottom, you'll never get the air out b/c its upside down.

You might want to invest $50 in a Motiv brake bleeder. It allows you to flush a large quantity of fluid through without all the pumping action.

Harbor Freight sells a vacuum tool that you can use to bleed brakes by yourself and it is under $20. Works awesome!!!
