clio 172
Hi This is my first post on here and I would like to let everyone know about my MOT today. I have a 53 plate clio 172 cup, which today failed on overall braking efficiency. The rear brakes were virtually applying no stopping power even though all the parts were in top condition. I was informed that the rear brake load sensor although all the parts were present were not connected, after discussions with renault and VOSA I found out that certain batches of 172's have the load sensor fitted but not connected, this means it does not conform to certain MOT standards regarding brake testing. The MOT assesor rang senior advisors at VOSA and they suggested doing an alternative brake test on the road instead of on the rolling wheels in the MOT station which is how it was tested by Renault prior to release. This test gave the efficiency required to pass the car but I doubt not all MOT stations would be as thorough as the one I visited today and i'm sure this oversite will lead to more 172 cups failing MOT's with no fault. My reason for posting is because from my conversations today my car could be the start of a batch of these now appearing at MOT stations and hope information helps you. One soloution was to tie wrap the actuator arm to maximum to pass the test but when you apply the breaks with nobody in the back the rear breaks would lock up earlier than they should and possibly cause loss of control from the rear tyres.
