It really seems like you should be able to get this to work with your current parts. Talk to the boys at your LBS and get some rotor shims to bump it out enough to avoid rub.
Awesome. I didn't even know something like that existed. Thanks!CheeseSoda said:It really seems like you should be able to get this to work with your current parts. Talk to the boys at your LBS and get some rotor shims to bump it out enough to avoid rub.
Edit to add: The last time I set up hydraulic brakes was about 5 years ago. The proceedure to align calipers may have changed since the last time I set them up. (/Edit)standard3x said:You might want to try a simple fix first:
1. Put the bike into a workstand or turn it upside down.
2. Remove the front wheel and check the bolts on the left side of the axle haven't come loose.
3. Insert a large flat bladed tool (eg a screwdriver) between the pads and prize them apart until they sit flush on either side of the caliper slit.
4. Loosen the mounting bolts holding the caliper onto the fork leg.
5. Replace the front wheel and make a mental note of how tight you do up the quick release. Each time you remove and replace the wheel, this is how tight it should be put back on.
6. Gently spin the wheel and watch the rotor to see if it is bent.
7. Now, center the caliper slit (never the pads) onto the rotor, accommodating any bends in the rotor the best you can.
8. Slowly screw in the mounting bolts a bit at a time each in turn until they have been fully tighten, but keep watching the spinning rotor.
9. Put the bike the right way up, raise the front end and spin the front wheel.
10. Grab the front brake lever and pull gently to reduce the speed of (but not stop) the spinning wheel. Do this two or three times.
11. Then roll the bike with the wheels on the ground backwards and forwards while pulling the brake lever harder and harder to stop the bike.
12. The pads will self center (a property of Shimano hydraulic brakes) when you complete this process.
13. Now take the bike out for a ride to dial-in the pads again. Put the bike into a low gear and pedal hard whilst partially engaging the front brake. The brake should work smoothly after 10mins or so.
