Failed on:
[*]Parking brake efficiency below requirements (12%)
[*]Nearside front brake binding
[*]Nearside & Offside stop lamps not working
When I got home the NS wheel was sizzling hot

Secondly I have replaced the rear brakes and all the internals (piston, springs etc). I released the handbrake and tightened the the nut under the van that the 2 cables join to but I still only got 12% efficiency in test. These are brand new pads so not run in at all. Do I just need to tighten them via that little service hatch on the back with the special tool?
Thanks
