Front Calliper Moving pads & pins

[haggis]

HI All, had a strange noise coming from my front suspension, so did a little strip down to take a look. The only thing I did notice was how loose the pads and retaining pins were, they are wobbling around in there. Does this mean the callipers have worn and need replacing ? the pins and pads both look good, 1/4" pins, Green stuff pads 3/4 of the meat left. 

 

Thanks

Hag

This sounds like you have caliper parts for type 16p unf and 16pb metric parts mixed up

the two designs have different pin and pad holes diameters

Im sure the 16pb has the bigger pins

Hello Hag, something for you to check. I replaced both calipers recently and was plagued with excessive pedal travel and was convinced the problem was air in the system. The problem turned out to be caused by dry caliper seals, making the pistons retract, the seals rolling back. I got round it by removing one pad at a time and very carefully pressing the brake pedal to push the one piston out slightly further than it would have been with the pad in place, then pushing it back in. In your case you could check the condition of the pistons for dust build-up or corrosion. This is assuming that the pistons are free to move, of course.

  I hope this helps but perhaps someone else could throw a suggestion in?
