Defender Brake compensatet

[Daz]

All, first thanks for taking the time to reply.
Secondly and more importantly know have fky working brakes. Bled them another two times and eventually they came back. Obviously there was air in the system somewhere but can't understand why bleeding them yesterday wasn't
Successful.
Thanks again, im now going to sit in the warm and watch the footy

Good its sorted.

The saga continues. Took it back for a retest and failed on rear brakes again. Bypassed compensator and made no difference. The pedal goes a long way down and you get some pedal if you pump it. It's been in the garage for a week now and they haven't been able to diagnose. They are now going me there is a brake balancer on the rear axle missing. Could this be correct?

for a 90? no, there is jsut that thing on the drivers side chassis leg.

Are you rears discs or drums?

no its not correct there is no balancer, has m/cylinder been replaced if it has you might need to adjust the servo rod if the drums are adjusted properly and front pistons arent retracting too far after applying brakes

 

[Daz]

It's drums at the back and it's a new master. How do you know when the rod is adjusted correctly?

little free play at the pedal though there must be some otherwise brakes will apply themselves

Are the shoes in the rear assembled properly? It isn’t hard to get them backwards then they won’t adjust or work properly for shi t

I got mine wrong and the spring held them away from the drums by loads and I couldn’t adjust them at all. I can’t remwmber what I had done but I think the shoes were upside down maybe?

Good ideas coming thick and fast - a less expert one, but in the past I had drum braked 110 that the highly paid main dealer only adjusted one adjuster per drum when there are two......nearly drove into the back of the first queue I came to. Does yours have 2 adjusters per drum and both adjusted....?

It does sound more like air or play somewhere else, but you never know.....

Hope all the other expert advice gets you there, cheers, A

What did it fail on this time? Brake imbalance on one axle can only really be air or a leaky cylinder.

 

[Kev12]

One more suggestion to throw in - are you sure the drums are OK? If the hard surface has worn away and you're down to the cast material then the brakes will be very weak

 

[Daz]

I'll check the shoes are in the right way and the condition of the drums.

 

[Daz]

Failure sheet says, rear brakes showing little or no efficiency, same reported for service brake.

DID You adjust the servo rod when you changed the master clylinder?

Also pressure bleed and up/down technique at the same time might get you a pedal

 

[Daz]

Pressure bled and pedal method.

Did adjust the rod but think I need to go back there.

 

[8ha]

have you tried clipping off all brake hoses try pedal and then release one pipe at at a time to see how it changes stroke of pedal I think some one has suggested this but are any brake pipes bulging under pressure

 

[Daz]

Will try that, I have checked all pipes for bulges but not clipped them off.
Them is for the advice

Update - garage have just called and sounds like there is something missing on the rear shoes. Some sort of metal connect r that joins the shoes together, so when you adjust them you are adjusting both. This must always have been missing but never been an issue on previous mots. Now to google what that part is unless anyone can tell me.
