Just fitted rear disks to my car yesturday and all seemed fine. Until i drove the car. No braking power until way down the pedal.

Not a problem i thought, just bleed the system. Which I have this morning, getting plently of fluid from each caliper with no air bubbles...... but still no braking power till the pedal is at least 2/3 the way down but feels fine when the engine is off. Also pedal does not come back up very quickly!

Any advice would be very much appreciated please

Oh how I've been here before.... - Fooking nightmare!

 

HELP!!!!

 

You may have to unbolt the rear calipers so the bleed niple is at the top. Even though you are getting no air from the rear brakes there may be an air pocket in the caliper cylinder as the bleed nipple is not at the top.

 

as above i had this prob b4... i put my cossie brakes on with nipple wrong way round...





check that first!


if not may b a problem with ur vacuum hose off the inlet???

 

also if you've left the rear weight actuating valves on, then you have to have weight on the rear wheels when bleeding to bleed them properely!

its a pain in the arse!!

 

aha! my bleed niple faces towards the rear of the car so I need to move the caliper so it faces upwards?

When i bleed the car the rear suspension ares where on axcel stands and so the bias valves where always open so i cant see that being the problem.

Thanks for the ideas guys

 

as moonie says had same problem last week

 

nightmare job....

but make sure you get the bleed nipple to the higest point and you won`t believe how much air is trapped!!!

give it a go and hopefully you`ll be sorted...

 

Sounds like this could be the issue then! Fingers crossed this solves the problem, I'll be out there first thing tomorrow taking the calipers off. If not its no Santapod for my car

 

What are you using to bleed the system? I found an eezibleed pressure kit worked well. And oddly enough over the course of a week my brakes did get better themselves...weird.

 

Yeah using a pressure kit which is hooked up to a tyre valve. works very well.

 

Dan,


Remember when I was bleed the system on thursday I showed you that the caliper had to be moved so the nipple was at the top to get all the air out.... .............. I knew there should have been a written exam afterwards to check you were paying attention in class

Just bleed them again with the calipers on top of the disk and air bubbles came out of both calipers so hopefully thats done the trick. just waiting for the paint to dry before putting the wheels go back on

Fingers crossed!!

 

Did you bleed the whole system or just the rears again ?

 

Hopefully..... the whole system (well thats what I sugessted last night)

 

All sorted!!
