Brake MC Help - June 16, 2011, 09:35 PM

Hey guys I have a 99 F4 with a 1000 front swap I did but i'm having MC issiues..


here are some pics






What I did was fill the rezie with fluid unbolt the lines from the calipers till it started having fluid coming outa them... then I bolted them back on the caliper then took the bleeder screw off and kept applying the break till the fluid was coming out of the bleeder then tighten the bleeder down then did the other side same way tighten it down... and then I go hit the brake lever nothing no tightness just a spong I dunno if the MC is bad or not ordered it from Ebay

Are you bleeding it correctly, even with fluid coming from the bleed nipples, you could still have bubbles in the line.

fill reservoir (making sure you never run it dry during the process)
squeeze lever
open bleed screw (open one bleed screw at a time)
close bleed screw
release lever (and keep repeating until you have a STEADY amount of bubbleless fluid)
repeat....

Is that what you were doing?

you do realize you need the wheel on the bike to have something for the brakes to grab on to right? You go squeezing the brake lever with no rotor and you're likely to blow the piston clean out of the caliper you will never have pressure if you are just squeezing the lever with no rotor. I advise you take your bike to a certified shop.

My statement was indeed assuming that the wheel was in place, along with a set of brake discs

no I filled the reservior unbolted the lines from the calipers
squeezed lever several times till brake fluid comes out of both lines
bolted lines back on
did the right caliper first
I open the bleeding screw and squeezed lever a few times till fluid was coming out of the bleed screw and closed the screw and repeat on the other caliper

Try doing it the "old fashioned" way that I described, I see what you are saying, but the way I described has always worked for me. I feel like your way still allows for air to sneak into the lines, also, make sure you don't get brake fluid anywhere its not suppose to, that shit will come back to bite you!!! my $0.02 of course

Ok you are doing it wrong.

follow this

bleed screw tight, fluid in master cylinder

1. squeeze the lever 3 times slowly. Hold lever down on 3rd pump. if you squeeze rapidly you run the risk of aerating the fluid and making big bubbles into little bubbles.

2. while holding lever down loosen bleeder screw on caliper farthest from the master. (left) tighten screw and than release lever.

Repeat 1 & 2 until no air comes out of bleeder

Than move to the right side and repeat

You might be the first person to ever use Nubbs and fancier in the same sentence.
