Brembo refurbishment

[David's8]

I started with the replacement of front discs and pads today but ran in to the problem of getting the new (Brembo) pads into the stainless steel pad guides. I had previously had problems 18 months ago with stuck pads and the current (Textar) replacements were also jamming when I took things apart to look at the potential causes of brake judder. I temporarily solved things with the textar pads on the old discs by taking 0-5 - 1mm off the sides of the pad backing plate which allowed them to run free. However, I dont want to do this with the new pads and discs and close inspection has shown that there is a build up of corrosion behind the s/steel guides which reduces the tolerance to an extent whereby the new pads won't fit. Unfortunately I cannot extract the torx head bolts (apparently they are held in place with Loctite) and so my conclusion is that I need to get the calipers refurbished professionally. I have been recommended by Big Redd (who did a good job on my rear calipers - but dont do Brembos) to try Pro-Calipers - a Brembo specialist who do a full re-furb including splitting the caliper. They are a bit pricey (approx £450 inc paint coating) but do use Brembo seals/bleed screws etc and use re-manufactured s/steel guides if the current ones are distorted. Others I have contacted are around £250 but dont do full split (whihc can be a problem I understand) and possibly dont use OEM seals.

Any advice/recommendations?
