Good till the last drop.

[obvious]I think it's time for new ones![/obvious]

 

And again I felt no difference in braking until the piston popped out and lost all braking capability

 

LOL... Honda Pace Truck. Hmm... maybe a lowered MD-X would work?

 

That right there is a worn out brake pad!

I've gone down to the backing plate before, but that's rediculous.

Try driving SLOWER!

 

what vehicle was this?

 

Tony's Chevy Xtreme pickup/pace car.

 

Not much we can do here...not even with the Panther XP. You have to look for ways to improve cooling as much as possible...even spraying water on the rotors and calipers.

Otherwise...larger rotors and calipers...but if you did that to P+'s on the 4500lb truck...you'll do just the same to XP. The XP will last longer and stop better, certainly, but you'll end up with the same result unless you check your pads often and change them when they get too thin.

Suggestion for a new rule: Trucks get teched after every session.

 

Trucks get teched after each LAP!

 

With water-cooled brakes, don't spray water directly on the hot metal bits! These systems work by taking heat energy out of the incoming air by using it to evaporate water injected into the airstream ahead of things that need cooling.

Seems like there must be some stock car parts that would bolt onto the front spindles of Tony's truck...

In all fairness, the truck was using Carbotech Panther + pads, and it STOPS the truck. The pads were used also at Summit Point for the last event last year. That's four hours of HP driving and whos knows how many hours of pace laps.

This truck should be the poster child for Carbotech.

Next time out, Carbotech XP with air ducts and hopefully water cooling.

wow...
have you ever seen a backing plate that "welded" itself to the piston?

 

This one had to be chiseled apart from the piston. The piston was actually rubbing against the rotor. Rotor was cryotreated and is really not that bad.

 

thats a lot of heat...
may you should have had the piston and backing plate and caliper cyro treated

 

I believe all Carbotech backing plates are cryotreated.

 

Our backing plates are not crygenically treated...they are industry standard cold rolled steel.

Andie, you just reminded me of something I've been wanting to ask you. Does a water spray actually work?

I would think that at those temperatures, the water would evaporate before it got to contact the rotors at all...or if nothing else, would evaporate so quickly that it wouldn't do much good.

 

over seas where they race semi trucks, they use it. so it's gotta work....somehow

 

no water = trucks loose brakes within one lap

The mechanism of evaporation is heat energy in the first place. Evaporating a liquid removes thermal energy and cools stuff. That's why we sweat.
