Hi Gokart00

When you think about RWR's solution, it does reinforce how the OTK system works.

He got his system air free and pumped fluid into the system to push the pads out until they were 1 mm off the disc and then sealed the system.

He then had a brake system which would give him a solid pedal without overheating as he should always have a clearance when the pedal was released.

As the pads wore down his pedal would start to need more travel to apply the brake pads but would still come off the disc when released.

At the end of the meet, he would then have to refill the system to make up for the pad wear which is what the reservoir does.

As to your problem, another thing that may be worth looking at is how the linkage is set up. I think there needs to be a small clearance between the master cylinder pistons and the two operating rods when the pedal is released. Then set the pedal length to suit your driver whist making sure that when his foot is comfortable on the pedal there is no pressure being applied to the system. if he is taking up the slack without noticing he is pushing on the brake that would push the pads out and touch the disc without any noticeable braking, but it would generate heat in the system.

I would also try filling the reservoir to about 1/3 of its capacity and then go and do 5 or 6 laps, if it still happens, look at the pads and see if they are against the disc. If they are, take off the reservoir caps and see if the pads release.

On my system, the last time out, my pedal started to go soft. I checked the level and one was almost empty, I topped both back up to between 1/3 and a 1/2 and my pedal was nice and solid again without fade even after 10 laps.

good luck
