4 piston maintenance
I'm not sure if anyone else has had to deal with this, but I just got a dual 4 piston caliper bracket from full throttle inc. Running new pre-machined honda pads connected to a brembo 16x18. Out of the box the power was incredible, but after a couple weeks of riding, the high idle I am running is overpowering it and the handbrake power feels like the single caliper I used to run. Glazed brakes? I cleaned the rotor with brake clean, sandpapered it and the pads and took it out the next day, there was a big improvement but I still had to turn the idle down a bit, anybody have any similar issues? I need my amazing handbrake power back!

Re: 4 piston maintenance
I'm gonna do a bit of test and tune with the rotor and pads here. I'm really hard on the brake cuz I do a lot of fast into slow and fast into stall tricks. The 4 piston fits my riding style perfectly. I think the pads might be dragging though which would definately create a problem.

Re: 4 piston maintenance
take the caliper apart and clean the pistons if its dragging...got the same set up and the only thing that gets me is i wear the pads out pretty quick...but i ride alot

+1. I've only had a problem when I bled my brake a bit to get some fresh fluid in the line and got fluid on the pads. Sand down a sec and a couple sessions later it's pretty mint. Haven't had a problem since.

My lever stays nice the whole time i'm riding but about 1 hour into riding its like the pads loose bite I have to pull harder on the lever to get the same braking force.
I just put a different rotor on with oem Honda pads and the same thing

Re: 4 piston maintenance
not trying to bust your chops just throwing advice, have you cleaned the actual pistons out in the caliper to free up some slack maybe

Re: 4 piston maintenance
i have to run dot 5 for the rears, otherwise i will have no brake from the 16x18..
also, i had to stand the bike straight up, hook a vaccum line to get the bottom caliper fed with fluid for the foot brake, but it doesn't feel as stiff as others i rode (alot of play) i adjusted the nut as far as it would go..is anyone using another foot pedal master to overcome this? the foot brake does work but u must mash on it a bit then it grabs like no other....using the foot pedal in this current condition would be wrecklace for sit down or staggered coasters..
