2 brake questions
I finally got the set of shimano 105 brakes I ordered from Nashbar today. I have two questions that are probably very basic, so please forgive my ignorance--I'm trying to learn:
1. When I opened the package 1 washer fell out---WTF do you need a washer for? Is this an essential peice? Where does it belong? I can't see a washer on either brake.
2. How do I tell which brake is front vs rear? They have different bolt lengths (I'm assuming for a reason)----also, is there any way I can use the rear brake on the front (of a different bike obviously)?
I know thats more than 2. Thanks for any responses.
