I've just stripped the front caliper and forced out the piston with the compressor and am astonished at what I've found! The inner bore is scored and was coated with coppaslip, the seal is toast and the piston is s pitted as to be useless. I need to replace the caliper body, seal, piston and bleed nipple at the very least. Strip the old damaged paint off and refinish.
Pricing the individual parts leads me to believe it may be cheaper, quicker and cause me much less grief to replace the lot. There are plenty of offerings out there but I have no idea what's good and what's not? Any pointers or recommendations most welcome.
On a positive note, the frame turned out really well and is hanging from the garage rafters. :D

These are excellent quality reproductions, a bargain price, and several members have used them and are very happy with them, and if you don't want a complete caliper, individual parts are available. https://www.davidsilverspares.co.uk/CB500K1-FOUR-1972/part_61408/

Why new body, how bad are the scores? If the piston is still a reasonable fit the body is serviceable, its the seal that does the work which you would be replacing anyway on a rebuild. A stainless piston can easily be made on a lathe, I have stainless bar if you have a lathe or a mate.

I am going to clean it up first and see if it can be salvaged. If not then it's probably the DSS replacement linked above by Mr Hairy or body 'A'. There are stainless pistons available online for around £28.00, so that's an option if it is usable. I don't have a lathe and have bought several mates but none with a lathe sadly. Even if one of us did, we wouldn't have a scooby what to do with it... ;D

I bought the Cruzinimage one last year for a 550. There have been comments about their rubber parts, but £21 all in.
Only listed for 500T at the mo, but same isn't it?

Body will be fine with new seal and stainless piston from the bay. You must, however, clean out the seal groove scrupulously as it is only the twist on the rubber seal that retracts the piston. 400/4, 500/4, 500 twin, 550/4, 250/360G5 are all the same caliper

Thanks all. Spent the whole day cleaning out the inside and stripping off the old paint. Stainless piston on it's way via Grahams eBay link and seal added to the DSS list. Should have it painted up over the weekend, then left a week to dry thoroughly and rebuild.
Thanks for your collective help it's much appreciated.

May be helpful.... I have a Suzuki GT250 X7 seal in my 500 caliper, we have a local Suzuki dealer and not a Honda one, works Ok and has done for 20 years.
