my car failed the mot on saturday on the rear wheel bearings
its got discs on the back but would the bearings be the same as
standard,the car is a s2 erst or would i get away with tweaking
them up to get rid of the play in them

 

Try tightening the nut that holds the bearing in place mate. If that doesnt work then replace the bearing... You will need to have an idea of what the rear disks came off, i.e. Cosworth, RS2000, etc, etc...

 

i think its got the brakes off of a 4x4 saph cossie,will try
tightening the bearings 2morrow but stuck if that dont work
