Having just stripped & cleaned up some of the later front Caparo calipers I was surprised to find the original spring clips had lost their temper (heat treatment) and gone quite soft

This is worth checking next time you have access as the later dumbbell style pins are held in place by the pressure of the spring clips

Saggy clip is the mucky one (new pair on the right)



This is location in the caliper, showing how they retain the modern brake pad pins

Part No. QP2740 from Rimmer Bros @ £1.74 ea inc. VAT

I keep some in stock now, just in case of faulty ones

BTW if you buy Ferodo pads you get 4 shiny new clips in the box foc

Or these if you want to get a set with pins

Ah, the later Caparo use dumbbell pins not the ye olde split pins, and if the thin steel springs loose there strength the pins can slide out

Oh well. I guess the split pins can be thrown out or used for something else, the springs are the same, and per unit cheaper than Rimmer Bros. I would change springs in a set anyway, especially if there's a design flaw and risk of retaining pins falling out!
