i set up a handbrake on my f4i running a 929 master cylinder and a second caliper off another f4i, now when i go to bleed it for some reason its not stiffining up enough, and its not that i dont know how to bleed brakes, anybody have any idea what the problem could be?

 

I needed a second person and it took me a while to bleed mine. Check and see how the line is ran and just keep tryin. F&%kin pain in the ***. Then make sure you try it again in a day or two. I made the mistake once of not checkin the day after did an SS grab the brake and nothing. It hurt.

 

if you bleed them alot, may need to check your crutch washers.

 

first of all, pull the res cap off, fill it full with fluid, tap the lever soft and quick, if theres any air bubbles coming out, hold the lever in for about 30 seconds and let it out again... if air keeps coming out, keep the cap off, and let it sit and gravity bleed for a couple hours.

then hook a clear tube to the bleeder valve, place the tube in a can of brake fluid,make sure every connection is as tight as possible, crack the bleeder and position the tube so that the fluid is flowing down and not back into the bleeder, and pump the brake until all the air bubbles are out.

ok i just used that method to bleed 2 handbrtake setups, one 900rr very similar to 929 and 1 radial so i know it works..

 

get a vaccuum bleeder.. takes 15 minutes and it's perfect... wa la especially with a dual caliper.. should work mint

 

i've used vaccuum bleaders and they're never consistent

 

that's because you have downsyndrome and can't work one properly

 

What exactly is this "gravity bleeding" and the theory behind it?

 

you leave the system open at both ends, keep the res full, and let gravity pull the fluid down. It works better on front brakes.
