I’m just refurbing the Brembo’s and all seemed to be going well… I’d had the lever arm and spring (for the handbrake) zinc coated along with some other bits but they’ve lost both those round springs and the retaining springs the pin goes through… 
Does anyone know where I can get replacements?

Some 90’s Renault’s used the brembo caliper but on solid discs not vented (caliper body will be different but other parts will be the same)
Cheers fella’s Dan at HPE has just sent me a picture via email with the words “you’re welcome” what a legend 
do you need some eye bleach?
