New brake lines, not bleeding?


Recommended Posts

So, I'm procrastinating on my wiring situation by doing some of the odds and ends work, such as finally bleeding the lines. I had replaced all of my brake lines and also installed my proportioning valve. I started with the right rear and it took many, many, many pumps (like maybe 100?) to get fluid back there.

 

But, for the fronts, I am in mystery-land. I have pumped a buzillion times and the reservoir level has not gone down at all and no fluid has come out of the bleeder screw.

 

Any ideas?

 

I certainly hope that my emergency valve hasn't gone south since they seem to be unavailable...

Jeremy,

Sounds like your MC needs to bled some more, or your pushrod isn't set long enough?

If you have a spare piece of hard breakline laying around, cut about 4 inches of pipe with the fitting on one end and put that on the outlet of the master cylinder with the open end in a bottle of brake fluid, then pump away. Once you stop getting air bubbles in the bottle of fluid, replace the regular (on car) brake line and continue bleeding at the calipers. I've found that once the MC is completely bled, opening the bleed screws at the calipers and letting the fluid gravity bleed for a cuple of hours (with the cap off the reservoir) helps to preclude air getting sucked back into the MC.

HTH.

I've left the passenger side bleeder screw open with the one-man-bleeder bottle attached. The caps are on, but just sitting on top (so no gook gets in there). Just sort of hoping for magical fairies to fix it I guess.

 

I didn't think that all that much fluid got out of the MC since the reservoirs were not completely dry. It does seem like that front circuit is full of air. I had considered bleeding the actual cylinder, just hated to do that since invariably fluid gets all over everything.

bleed the master

 

heres how

 

use a 12" section of vacuum hose put it on the master bleeder and put it back in the reservoir - open bleedeer half turn- SLOWLY pump pedal and it will recirculate.. do that till you get some feel

did you put the spacer back that goes between the master cyl and the vac booster? bleed the master?
