Rear Brake issue

[Wobba]

Thanks for the tips both...

I have left it to soak overnight in WD40 - tried to undo the nuts but they were rusted solid, shall see if there is any movement tomorrow

The little nut on the end should come off quite easily tbh. Give the area a scrub with a wire brush. Hold the bigger nut to counter as you unscrew the small one. Should be easy after that.

you really need a penetrating oil WD is not really suitable i tend to use duck oil or whatever is available and see how u go just be patient and a bit of heat always helps so get the blowtorch fired up

Well just had a go at it, managed to loosen the big nut off but the little nut is jammed solid, it just moves the whole thread! All fun and games eh. Will have a proper look at the weekend though.

Out of interest does anyone know the cost of a new valve from renault?

Just over £100 but they are on back order from France.

I was unable to unhook the spring from the rear arm without loosing the nut at the front. As the brake pipe unions were siezed solid into the bias valve, I stripped the valve down insitu and used long nose pliers to work the 2 internal valves.

After renewing the osr caliper, changing the pads and brake fluid, the rear brakes pulled 177/191kg on the MOT handbrake test
