I always do my maintenence at least every 1500 miles or once per year.......I have already changed the fluid 3 times this year trying to see if maybe there was something stuck in the lines(air bubbles) or somthing but it never did a thing for me.

 

Can I find a rebuild kit online? Is is only Master Cylinder parts or caliper parts too?

I'm getting new lines and since I'll be installing the new lines, I figure I'd do the MC and calipers while I'm at it. That way I'm guaranteed no problems with brakes.

 

you can't buy a rebuild kit..you need to go to ronayers' microfiche and get all the rubber pieces from both the MC and calipers.
if they aren't leaking, don't rebuild them. just clean them up.

 

My M/C is suspect. The lever travels more than it should. About 1/2 for full brakes. I went today and felt a 06 F4i's brakes....mine should feel better. I can pump a little to make the harder then they go back again. There's no air in the system. I've bled and so has the dealership.

 

I finally got a resolution for my braking problem and thought I'd share with the group.

I bought a MityVac to change my lines, I got some new SS ones and had a problem getting the right one to work properly. After noticing that the left holds a vacuum steadily I started to look closer at the right caliper. I found that there was an air lean around the threads of the bleeder valve (WHAT?) I wrapped teflon tape around the threads and put the valve back in and VOILA! Instant braking action and steady vacuum pressure.
