caliper question- stainless brake bleed screws?

Post by chopperoli »

Has anyone used these? to stop them seizing etc. I believe they are M7x1, not sure on the length if it's highly important.

Also are the caliper slider bolts M8 or M10 ?

Better off with mild steel ones, they are closer to aluminium alloy on the galvanic scale, therefore have less tendency to bimetallic corrosion.

Stick with the standard bolts and to stop them seizing smear a little copper grease on the threads.

Tom, I'm pretty sure the front calipers are not aluminium? But maybe the rear slave cylinders are.
The slider bolt question was thread size not allen key size (I have both key sizes in the tool box!) because I know Mk1 Golf sliders were M10 solid shoulder bolts, whereas Mk2 Golf / Polo etc with the same calipers (VWII 239mm) have M8 caphead screws which clamp down on a separate slider sleeve. So I wasn't sure what Roccos would have. Maybe it depends on the year. Guess I'll find out the hard way :)

sorry you right chopperoli , early ones are a solid pin with m10 thread one side that use a 7mm allen key , later are sleeves that use a m8 cap screw - 6mm allen key , calipers are steel
