Got on the front brakes yesterday! Interesting find! Crappy mess as i expected! Completely down to metal! The left side was worse, inside shoe was completely gone! Remnants of shoe inside piston. Never seen one this bad , i just ground it back down with the grinder reinstalled and working perfectly, see the remnants of the shoe i dug out of the piston laying on the tire in the background. Had to reinstall it with a c clamp my caliper tool was to large to fit in the tiny caliper.I have new calipers ordered for both sides, but its working good now i suspect the bad one will start leaking. Caliperss are so cheap 25 for set of 2 new caliper is cheaper than piston and seals. I have one more of these Eigers to do, i have the front brakes working with no issues but never pulled the caliper to check it out, rears not working at all, while its fresh on my mind i think i will do it also, plus thats the one i need to mount the new tires on. That will be an interesting venture, i usually take it and have them mounted but the cost has gotten so expensive i decided to do it myself. I bought one of those Harbour Freight portable tire changers cheaper than the cost of getting them mounted, very interested to see how that goes, but that will be another thread.
