Hi guys, sorry I've not been back to you, mad busy at work. Anyway, got my car back a couple of weeks ago, serviced and Mot as well as the brakes. They did admit that the young mechanic that originally worked on it messed up and didn't top and tail the pads, also broke the block on one of the braided lines. I suspect that he also broke the caliper as it was the same side that the braided line broke on, but can't prove that and they didn't admit to that one. Dave Greenwood eventually stepped in and got everything straight for me. Still got my ABS, ESP off, Traction control light coming on which was happening before the new brake parts were fitted but got a new Nissan brake switch ordered so will hopefully fix the problem. I'm booked in with Tarmac sport in January for more work I want done, so thanks guys for that recommendation, just over an hour drive from me so I'm sure it's worth the trip. Would still recommend lockwood and greenwood to anyone for service and MOT but must admit I was let down by them on this one. Just also want to say another massive thankyou to ZMANALEX who really went out of his way to help me.
