CP5200 calipers

[Basil Brush]

Does anyone have any 6 bolt CP5200 calipers they don't want? I've cracked my near side one trying to get one of the bleed screws out whilst stripping them down for a refurb so either after a single replacement or a pair.

I appreciate that it's too late for you but for anyone else trying to remove seized bleed screws I recommend using a socket and T bar, never a spanner

Even with that set up, in a vice with gentle heat and having been soaked in penetrating fluid for a few days there was no way it would have come out intact. I'm guessing the build up of corrosion had weakened the casting around the threads. At least the other three came out ok, so technically I only need half a caliper!

That is a strange failure mode

Usually the bleed nipple snaps, leaving half stuck in the caliper

I've heard it's possible to remove the remnant using spark erosion, though I've no experience of that myself

Maybe I wasn't being as careful as I thought!

Luckily someone on here has a spare they don't need so not as expensive a lesson as it could have been.

Yeah spark erosion works, I had to get a couple of mine out that way in the past.

For a replacement try the TVR breakers and also the Lotus forum section, my mates Exige S1 has these calipers on the front.
