Hi, hoping to get some advice I've had Guide RS brakes on my bike for about a year, and in the last few months the levers have gotten a bit slow to return. Basically when I squeeze them, the lever doesn't spring back very quickly. Doesn't seem to impact the operation as they grab hard and there is no indication the pad is rubbing on the disc due to the slow return. They brakes are a bit spongey, so i will be bleeding them in the next couple weeks, but after some reading it doesn't sound like that will fix it. There have been a few posts around where people had something similar and SRAM fixed it under warranty, but I don't have this option as I bought them 2nd hand. I wash the bike after every wash and usually re-lub everything with JL69. So not sure if I should not be doing this, etc. Anyone else has similar issues/solutions?
