Brakes dragging

[bob888]

I recently relined the brakes. I bled the system and had the caliper pistons pushed all the way in. All seemed OK and actually braking well BUT it seems harder to push back into the hangar and when I jack it up and turn the wheel the brake is definitely dragging, on both mains. Suggestions?

Had this happen - cause was a rolled brake caliper O ring. Replace it and problem fixed.

Had this happen while in phase I. I found that with my heels on the floor and feet resting on the rudder pedals, while on the taxiway, the ball of my foot was applying a small amount of pressure to the brake pedals, which caused the brakes to drag. Assuming the RV10 brake/rudder set up is the same as the side by side RVs (I have not built an RV10), I did two things, one was to install return springs to the top of the masters to hold them in the released position until pressure was applied, and two was to add rudder tube extensions which keep my feet off the brake pedals. I made the extensions myself but you can now buy them pre made here from a VAF member. The rudder tube extension was most likely the majority of the solution.

Hope this helps!

Cheers,

If you have a parking brake.. let me know and I?ll suggest some fixes.

Make sure the pedals are fully retracted, sticky pedals that don't fully retract when released will cause the brakes to drag.

Response to Plummit...Yes on both mains. Response to others, not related to non-existent parking brake and I don't think a pedal problem. Thanks for your feedback guys.

Some dragging of disk brakes is normal. However it shouldn?t be any harder to push around. Lift a wheel and spin by hand. It should spin relatively freely although some contact drag may be there.
Check your caliper pins and make sure the pads can move freely. If not, clean them out and polish them up a bit. You might also check for warped rotors while your at it especially if the dragging seems inconsistent.

a bit of dragging is not uncommon with new rotors/pads and sometimes with just new pads. I wouldn't concern myself until the brakes have been exercised with a couple of moderate to agressive stops.

I ended up making a couple of shims with .025 aluminum and inserted them between the caliper parts. Problem solved for the most part. I expect to take them out at some point when the pads wear down some.
