Well i wasnt sure if there was an easier way to work the air out of the caliper with it being so big and having so much internal area to it vs a regular 1 piston sliding caliper. It only has one bleeder at the top of it

What kind of caliper? My Wilwoods have 2 bleeders, one per side. I bleed like normal, but now I have 6 spots to bleed instead of 4.

if it has four nipples or two that are opposing, you only need to bleed the upper facing nipples

Right. Never, never, NEVER use the bleeders at the bottom for anything. Only the ones on the top. (Air rises...)

So if the caliper has four bleeders, treat it as if it only has two (the ones at the top). Start with the inside bleeder – closest to the master cylinder – get all the air out. Then move to the outside bleeder.

Move to the next caliper. Repeat.

When in doubt, think like an air bubble...

My only has one its a rotora kit. SO no special trick in getting the air out of them? Just a lot of bleeding?

Only 1 bleeder? That really doesn't sound right? I would expect a 4 piston to have 2 pistons per side which would be a bleeder per side.

The way I've bled dual bleeders in the past was to open both bleeders with lines on both bleeders. Keep pumping the pedal until fluid comes out of both bleeders. Then tighten bleeder #1, and do normal bleeding on bleeder #2. Once that is good, tighten bleeder #2, and do normal bleeding on bleeder #1.

This method seems to do the trick on new calipers that will have substantial air in the lines.

If you do really only have one, then I would expect the normal bleeding procedure to work just fine.

My Rotora brakes have 2 nipples per side on the top.? which kit do you have?
As per the instructions, Right outer, Right inner, left outer, left inner

Call rotora and check , they should have 2 each side.

I have the hardline at the bottom that connects the 2 seperate sides of the caliper but Im pretty sure the only bleeder is on the top outside. Ill definitly give it another look and another try of bleeding. I thank you all for teh insight and ill get back to you asap
