Hydraulic disc brakes
What are the most common causes of a sticking caliper. I overhauled the rear,juicy 5's,in the rear. Just cleaned with a light home, bless it and all well. 3 month later the front is sticking,why?

surfaces and pins that are supposed to slide are either bound from grit, or gummed up. Clean and apply heat tolerant antifriction grease between those areas.

The best repairs on older Juicys is replacement with brakes that are not terrible. Your problem is likely that the seals are swelling and displacing more fluid.

By now Im sure that everyone knows that I am a great promoter of disc brakes. However I do think that hydraulic brakes are needless complication. They are higher priced, and harder to fix.

More the point, that Avid brakes have a very bad rep. Hydraulic brakes aren't perfect, and are being refined every generation, but they offer superior performance & self adjustment over mechanical disc, and with the cost being the same or less for MTB discs than mechanical or rim brakes, it makes would go for them (preferably Shimano) everytime.

Hyd. Brakes enables less shoptime maintenance for 'adjusting' brakes and setting the cable tension. It may inflict fear to those that offer services to upkeep bike maintenance. Which if a poll was done which is better, the results (if enabled) might reveal who does it as a hobby and not for profit.

I just recently bought 2 mountain bikes with hydraulic disc brakes. One was a new lower end bike I bought on eBay with Shimno M315 hydraulic brakes for my 14 Y.O. and the other was an uncompleted project bike I bought with Avid Elixir 5.
The Shimano brakes were easy to set up and have no rubbing issues at all but the Avid brakes have been nothing but problems. I can't keep them from rubbing the rotor. I get everything adjusted on the Avid brakes and have no rubbing but before the ride is over I'll have some dragging from the Avid brakes. I even replaced the rotors thinking the ones that came on the bike wasn't true but I've not had any better luck with the new Avid rotors.
I plan to replace the Avid brakes with a set of SLX to match the rest of the group I used on the bike but haven't really used the MTB like I believed I would.
I should have bought a something like a hybrid instead of building a hard tail MTB, so my opinion may be somewhat jaded.

Is the pad preload overcoming the retension? Maybe there's hardware missing within the caliper that would prevent the unwanted drag?
