Ordered from EBC - Believe they are CAPARO but it says caliper is Lockheed on EBC website - hope that wont be a problem.
Failed to locate W clips.
I have just looked on the Rimmer site, searched for “brake pad clips” and they are the first item to be shown. Part number QP2740 @£1 +vat each. P&p is about £3. I know they fit as I have used them on CAPARO callipers.
The Lockheed calipers take similar pads but the retaining pins are different. You wouldnt need the W clips for those.
Read all about it in Dave’s book?
