While practice riding yesterday I checked the rear brake rotor for heat (something I do periodically) after using only front brakes. The rear rotor was very, hand burning hot even though the front brake was easy to touch warm. The rear brake was dragging so hard the tire spun only 1/8 turn. The SMC assembly moved its 1/8 inch easily. When I was checking the tire pressure before the ride it turned 1 turn. I road it the 2 miles home. This morning I check the rear tire spin and it spun 1 turn again, huh? It used to turn 1 1/2 turns.
I also checked the SMC this morning. It moved easily. I had the good wife spin the rear wheel and activated the SMC, nothing happened. The rear wheel continued to spin like nothing was on it for the rest of the 1 turn spin. I believe the SMC piston is stuck in the down/pressed position. I've had an SMC failure before and revived it two years ago. I'm just going to replace it with the whole assembly, just don't trust this SMC any more.
I double checked John's "avoiding the pitfalls" article and saw something I didn't do. When I put the new rear pads on I just pressed the pistons in without the outer nipple open. I guess this action started the failure I'm experiencing with an already weak SMC. Thanks for the great article John.
Question for those that have replaced the SMC before. How did you relieve the pressure in the brake line without spraying brake fluid every where? I'm thinking that opening the PCV nipple will work.
Hope I get the part, fixed, and tested before TentSTOC! All my sources for discounted OEM parts use Ground FedEx and no overnight, 5 to 10 days starting Tuesday. Think I'll go by the shop and pay more for a 4 day ship. Any sources that can do it quicker?
