Replaced tires and brakes today, not front left caliper is sticking only way to release it is to remove the caliper.
So how difficult are they to rebuild?

Calipers are easy...even I can do it. Only two moving parts and 4 seals for each caliper.

Not that difficult,just make sure the pistons aren't pitted or rusty.Parts are pretty cheap from HDL.If one piston is stuck block the others off with some woodblocks and use the M/cyl to pump out the stuck one.
Change your brake fluid once a year and you'll have very few problems with your calipers.

+1 on changing out your brake fluid at least every other year. DOT 4 is very hygroscopic and the water will form a sludge.

+1, they are surprisingly simple. Somebody on here had a nice set of pics that alleviated my initial fear of taking them apart. Maybe you can find the thread... |

Sounds more like the front axle may not be positioned correctly. This is a pretty common error and the symptoms you report are well documented. *** |

Not sure what you mean by that? Before applying the brakes wheel spun freely, after applying the brakes to adjust the calipers, spun the wheel again and hit the brakes and it looked up on the left hand side and would not release. Have to remove pads and recompress the pistons to remove the caliper.
Rotor are not bent or mis-aligned.
Shed some light please.

If you don't mash your axle all the way back in (all the way flush) with the fork, the caliper won't do right... Here's one that is not flush... see, it's sticking out a little...  Easy thing to check, easy to fix, hope that's it... -Mike |

Mine is in tight/flush with the fork.
Found the problem, scored piston...so I will be replacing them. More than likely I will replace all four on the front.
Thanks

OK, changed the pistons, and changed the fluid...can not get pressure at the grip? Anyway to bleed the air out faster?

I use a syringe with a little piece of hose on it, hook it to the caliper bleed and suck some fluid down from the reservoir... once a little fluid moves into the system, the lever will pump it like you want. A bunch of people here use a "mighty vac"... -Mike |
