Hi - just renewed pads all round on my daily 29 l 10 - took it up for mot and failed as the rear pads are not gripping the discs allthough the hanbrake works on both rear wheels. The caliper piston appeaears not to move when brake pedal pressed down. I screwed the calipers in to get the new pads in. Any ideas anyone?
all replies appreciated

Yes it was the load sensor - pushed up linkage and got fluid to the brakes - bled system and got M O T pass - Many Thanks my friend.

not quite sure how they adjust , on some vehicles the adjustment is on link that connects to axle. -if you disconnect link from axle and lift it up towards floor [simulating full load]do you get any fluid to calliper -if so its possibly adjustment,-if still no fluid then valve must be siezed. hope this is of help to you.

Thanks - you might be right - Theres no fluid getting to either rear caliper - Cracked a bolt on top of the valve with engine running and pedal wedged down - fluid flowed out but still none at calipers - took rubber boot off and cleaned corrosion inside but dont know how to adjust valve - suppose its the bolt in the middle of the valve body? Do you know if they can be unseized as new ones are an arm and a leg - will have another go at it tomorrow - dont want to be defeated and too skint to get the garage to do it - any further advice greately appreciated.

Many thanks

have you checked load sensing valve,it may be siezed or want adjusting to give more pressure to rear foot brake.
