Uneaven Disc Pad Wear - MTB

[New Landy new life]

My discs have reached the end of their life and at my last race the spreader spring ended up getting jammed into the disc and caused hell of a noise and rubbed for the last 15km’s.

When I removed the pads I noticed they have a camber worn into them. i.e. the top of the two pads are thinner than the lower.

Is this an indication of poor alignment or problem with the pistons.

Any ideas?

Bike is 18 months old with 1500km on the pads

This is normally due to the callipers being fitted skew, they are not pushing flush/90deg to the disc.

 

Fit new ones and realign the callipers all should be fine then .

if i get 1500km from a set of pads i would not care at all how they look.

I dont think the calipers are skew, if both are thinner at the top there is another issue.

If the caliper was skew you would have one pad thin at the top and one thin at the bottom.

If worried about calliper alignment. Loosen the calliper, spin the wheel real fast. Grab the brake level and dont let it go. While still holding onto the brake lever, retighten the calliper. You can now let go of the brakes once the calliper is tightened.

 

But as said above, its time to change them anyway, so it doesnt matter how they look.

I get 1500 km's because I don't use them much downhill

 

Thanks guys, I did do the alignment as per some youtube video guide by loosening and grabbing the breaks and then tightening the caliper bolts. Will replace and do more frequent checks to monitor wear
