Hi Dave. Thanks! Yes I think they look great, just looking forward to getting the car back with them on now.
For the record I used a place called Brake Caliper Refurbs based in Rochdale. I thought their service was very good and at a reasonable price. Jonny there worked hard to get a decent finish on the tricky calliper. Only slightly negative point I'd make is just to take the time estimate with a pinch of salt. If you have calipers that have never had a major refurb and are 25yo then expect closer to month than a week for them to be sorted because issues will arise.
Better waiting longer though than getting a bad job done quickly. Having said that, they are not on the car yet, so I only know they look good and not how well they work.
