I'm stuck again with my brakes. Have sorted all the break lines etc and bled the don't callipers but the rear drums just won't bleed. U
am using an eezibleed as I am by myself and I am getting no bubbles no fluid, nothing out the rear drums.
Help?!
Single master cylinder?
Pressure ok in the easibleed?
have you got a balancing valve for the rears? maybe that needs opening?
Single master cylinder.
Eezibleed pressurised.
No balancing valve i am aware of or can see. kit did have pressure reducing valve which I have removed.
How does the pedal feel, solid, spongy, or hitting the floor?
Have the fronts bled OK?
Is the pedal returning all the way back up?
Is the master cylinder piston returned all the way back? If the piston does not come all the way back beacuse the pedal is restricting it or it's
a bit sticky then the port to the reservoir will not be opened.
If the master cylinder appears to stroking correctly, try slackening the pipe at the master cyinder and giving the pedal a pump to see if fluid is
present at the MC, if it is then tighten the connection and do the same again working towards the back of the car until you find where the fluid is
not appearing.
If you can't get fluid at the MC then post back and we'll go down a different road.

balancing valve = pressure reducing valve.
I guess you are looking for a blockage in a pipe then?
starting at the M/C try slackening the pipe fittings one by one to see if fluid comes out and work your way along the system to the back to see where
it stops coming out.
Have you checked your nipples are not full of crud or paint or other?
Steve.
New slave cylinders/nipples or old? If old check the nipples aren't blocked and poke something up the holes to make sure they aren't blocked. Quite common with old cylinders.

Also definitely fluid as master cylinder
Managed to get a bit out but was black! Re bled fronts and got same but eventually ran clean so now doing rears again.
Ok so managing to bleed all four corners but pedal still soft and going to the floor?!

Front calipers on the correct sides? bleed nipples need to be at the top otherwise you won't get all of the air out. Had this problem myself before!
Front caliper nipples are at the bottom, so these need swapping round?
I bought the kit part built and as far as I can tell the master cylinder and front calumets are the only bits that weren't new in the braking
system. Drums look new and obviously all new lines.
Fronts bleed easily and quickly rears bleed with difficulty and slowly.
Yep deffo need to be at the top! I spent ages trying to bleed mine, a mate came round we swapped them over and it was bled in ten minutes!
Balls! Will have to swap them over!
Let us know how you get on
Will do. With the way works looking this week, stoneleigh next week and a full packed family weekend the next I won't get chance to do anything now untill 25th may!
