Before all the jokes come in this is my other car. Failed its MOT on excessive brake force fluctuation.
Now I'd expect something described as excessive to be noticeable during driving, but it's not at all. I couldn't feel a thing unless I drove down the hill at 1mph, and even then it was only just detectable. I read online that the max allowable fluctuation is 60% and there is no way this is 60%. I measured the runout at 0.05mm on one side and 0.02 on the other, so there's a thickness difference of between 0.03 and 0.07. Surely that's not excessive?
And yet again I'm away and my wife needs the car so I have no choice but to cough up to yet another ****ing garage. I ****ing hate garages. £160 for a 30 min job ffs.
****ing fuming.
sounds to me like you dont know what brake force fluctuation is if your measuring run out as a means to end it.
I know what it is of course, read the post. What would cause fluctuation? Variable disc thickness. They told me the discs were warped, that's why I measured the runout. And I don't have a brake force dynamometer at home.
Molgrips seriously, get the car up to my VW man in Cwmcarn to give it proper check over and assesment of all issues.
That was the Prius, but give me this guy's name, other car is still not fixed...
Drop me a mail and I'll fire it over, he won't do Prius s (prii ? ) VAG and Porsche only (very good on my GT3 😉 )
