CUP fails MOT yes another one

[Big Bob]

Hi guys as title states my cup has failed its MOT today on the rear brakes now i know that vosa even mention the brake issue on thier web site but does any one know what a cup should make on the rear brake pressures as the right did 50 and the left rear did 10?

is there a minimum figure set by VOSA if so does any one know what it is as they dont want to answer the phone today ?

thanks in advance

Sounds like either your rear left caliper is fked or it's got air in it perhaps.

Try checking the piston out, and bleeding the brakes would be my knee jerk reaction.

may well do that hoff just blled the last bit off the caliper

"just blled the..."

Eh?

Sure you'll get some more specific help by the end of the day. I don't have a Cup so not sure on the specifics.
