I have a October 2003 147 GTA that had covered 21000 miles when the brake warping first became apparent. I'd been to North Wales for a few days in July and the weather was amazingly warm, driving on those fantastic twisty mountain roads must have taken it's toll on the brakes however as on my journey home I was experiencing violent juddering when braking from motorway speeds. After a couple of days of doing my own brake checks I was convinced that my brakes were warped, I could even feel it a slow speeds so I knew contacting the dealer was the next step.
I first tried Caledonia in Warrington, they new of the problem but due to my mileage they said there was nothing they could do under warranty. I then tried A. S. Jones in Flintshire North Wales but they hadn't even heard of the problem and were not very interested. I then tried Mangoletsi in Knutsford, Cheshire, they'd experienced the problem before and were in fact dealing with a 156 GTA with the same problem at that time. They asked me to bring the car to them so they could check it for themselves which I did and they agreed the brakes were indeed warped. Mangoletsi then had to start a case for the upgrade with Alfa Romeo themselves, this took a few days but I was then contacted and booked in at the first opportunity. The work should have just taken a day but one of the calipers had not turned up, this just delayed things a little as the next day it arrived and the car was soon ready. Though the upgrade was completely covered by Alfa I had to pay for new pads due to my mileage, though I'd rather not have to they were only 67.00.
I was thoroughly impressed with the level of care received from Mangoletsi and in particular Paul on the service desk. I'm also very happy with the upgrade the discs and calipers look and work great.
