Brake caliper problems

(1/3) > >>

Saesneg Shaun:
Another day, another problem.

I found why my front brake was dragging and hardly worked. The piston was catching on the little brake pad retaining screw poking through the back of the pad and pushing the pad at an angle so I only had about 25% contact. This seems too have caused the pad to tilt in the caliper and jam.

I've shortened the screw slightly to avoid catching the piston (which now has a nice groove in the lip) but should there be a dust seal on the piston and pad?

Bryanj:
What brake pad screw, there isnt form

Saesneg Shaun:
Its the piston side pad locating pin that screws into the metal backing of the pad. Its was too long and fouling the brake caliper piston lip

Saesneg Shaun:
this one. You can see slight damage to the lip where it rubbed before I trimmed it.

Saesneg Shaun:
Ok problem sort of solved.
My bike is completely missing the seat pad part number 45151-300-000.
The 'mechanic' who previously owned this bike must have thought it not necessary!

I'd assumed the locating screw/pin was aftermarket and too long not that a whole piece was missing from the setup.

I ordered some stuff from DSS last week. Now it looks like I have to pay their extortionate delivery charges again!
