caliper overhaul
« on: 12 August 2014, 15:06:46 »
What's the best method of bringing back to new ( or as close to as possible) brake calipers? Just got myself a set of 4 off elete Pete and want to spend some time on them.. Lets call it a little project to ease boredom  ;D

As far as the mechanical parts go just a dust seal, square-cut seal and new piston needed (assuming that your piston is all rusted/pitted etc.)

I haven't disassembled them yet but all look as rough as a bears arse.. Don't want to send away to be shot blasted but want to clean up as food as I can and repaint and reseal.

Once cleaned up, I paint mine with Hammerite (well the smooth version).

In terms of mechanical working order calipers are as straight forward as they come.

However, you will need to replace the piston cos I guarantee it'll be all rusted and pitted and it's this pitting that tears up the square cut seal. So, square cut seal, dust boot and new piston.

Then as for painting them and making them look pretty.............. no idea ;)

Out of interest what would a set of replacement pistons and seals set me back?

From somewhere like Brakes International you're talking about £15 for a service kit (seals, boots etc) and £15 for a replacement piston.. Or £46 for a whole replacement (rebuilt) calliper (plus a £18 core charge refunded when you return your old ones) that arrives shiny and looking brand spanking new.

It's hardly worth the bother to DIY something that will never look as good as the rebuilt (media blasted, plated etc etc) one.

Brakes International - facelift v6 for example

Thing is I already have a full set of 4 in the garage and just wanted to have a play with them so to speak. They don't need to be factory showroom condition but as clean as I can get using elbow grease... But would like new seals and pistons in them
