Pro-Tech On Car Brake Lathe vs B7 RS4
Posted: Tue Sep 01, 2009 7:21 pm
So as mentioned before I have had for some weeks huge vibration from my brakes which Audi diagnosed as being rear disks warped. Replacement price, minimum £450 for disks and then new pads also so all in all circa £700.
That would be the cars third set of disks if I did this so I wanted to investigate alternatives, one of which was brake skimming, something Audi would not recommend you doing (largely because they lose £700+ of revenue and don't have a lathe).
So today I had my car booked in at Revolution (http://www.revolution247.com/home-page-1-0.html) to have the rear disks skimmed using a Pro-Tech on Car Brake Lathe. I will say now that only the rears can be done this way, floating disks like the fronts would have to be taken off and skimmed.
As always the staff were courteous and after some initial problems accessing the caliper fixing bolts and lossening them off their tech got on to the job. I would have taken pics but their viwing gallery window was paryicularly clean and reflecting everything behind me in the showroom so the pics I did take were rubbish.
However 2 hours later and the car was done. Effectively the lathe has taken off the bare minimum which roughly equates to about 1000 miles worth of normal wear. Now like new disks you have to be careful with them to start off with but suffice to say the vibration appears to have gone although because it is a lathe the surface still need cleaning up to be uniform as it is rough at present.
I will report back over the course of the next couple of days to tell you how the car feels but total cost for the two hours, £69. Better then £700+ If you want to find a lathe local to you... http://www.skimmydiscs.co.uk/find_a_lathe.html
Coupled with my wheels having been put on a Hunter GSP9700 balancer yesterday and the car is feeling how it should. One trip to Audi tomorrow to sort out front suspension and one exhaust actuator and it should be how it was meant to be.
