rover 25 - back brakes 'grabbing'.

[acm5497]

The back brakes on my 2000 plate Rover 25 have started to 'grab' before front braking takes effect. The servo does not appear to be the cause. Any ideas?

remove the drums and check that ;
1) there isn't a broken spring.
2) there is enough friction materiel left.
3) there isn't a leak in the slave cylinders.
4) there isn't to much dust and debris floating about.

these are not in any particular order of importance.
( this assumes that the rear brakes are drum brakes)

This is the classic sign of a faulty load compensator: the purpose of this is to distribute more brakeing force to the rears if theback of the car is loaded with passangers or luggage: if it's broken then you will be getting maximum braking at the rear all the time, loaded or unloaded, which will cause the rears to lock up if the car is unladen.

On the 25 it's on the bulkhead-looks like this:http://cgi.ebay.co.uk/Brake-compensator-valve- Rover-200-25-MG-ZR-ABS_W0QQitemZ4590047024QQih Z006QQcategoryZ10414QQssPageNameZWDVWQQrdZ1QQc mdZViewItem

sounds like either the brake shoes are adjusted up too much or that the lining from one of the shoes has came adrift and is wedging the drum. take the drums off and check.
