i recently purchased a mk5 1.7cdti and on the MOT paper a advisory notice was issued with the following problems.

Advisory Notice issued
Nearside Rear Brake pad(s) wearing thin (3.5.1f)
Offside Rear Brake pad(s) wearing thin (3.5.1f)
Front brakes only just met the front brake imbalance requirements. It would appear that the braking system requires adjustment or repair. (3.7.A.2e)
Child seat fitted not allowing full inspection of adult belt
Slight play in both sterring tie rods.

Would like to know what type of brake pads i need?
Also is this an expensive job to fix all the above?

Thanks
