Ventilated Pistons

BrakeTech Ventilated Caliper Racing Pistons (Complete Front Axle Set)

BrakeTech Ventilated Caliper Racing Pistons (Complete Front Axle Set)


Better than Titanium! - 30% lower heat conductivity

Recent OE/Original Equipment calipers have come a long way in terms of both performance and design.

Far more rigid than their predecessors, the current generations from Brembo, Nissin, Sumitomo, Tokico and others are ultra-stiff and relatively lightweight designs which have been instrumental in elevating stock braking performance to new levels.

But, unfortunately, they’re still using problematic Aluminum pistons – lightweight, yes, but also highly conductive in providing a huge heat path straight into the hydraulics.

BrakeTech has now addressed this with these precision engineered ventilated Stainless Steel pistons of proprietary material - which feature a 12 ventilation holes and a unique castellated reverse chamber for increased fluid capacity - that all but eliminate those shortcomings.

"I was racing at Donington Park at the weekend and finally got some dry laps to give the brakes a hammering!

Must say Im very impressed with your ventilated pistons - on the National Circuit there are two heavy braking areas close together and with the alloy pistons fitted there is a noticeable drop in braking power at the second braking zone (as the heat is still built-up in the pistons etc). With yours fitted I can get full braking power as the pistons have recovered and ready to do their job. Plus when I get back in the pits and put the tyre warmers back on - theres no binding of the calipers (like there is with the alloy pistons).

I showed the pistons to a few of my racing buddies and they were impressed."

"Replacing the piston on your new KTM 450 may be one of the best mods on the list but its not the piston you think. I’m super hard on rear brakes and have even melted the rear caliper itself. Brake Tech has redesigned this brake piston to hold 20cc more brake fluid in your rear system as well as drilled holes in the end to help distribute the heat better. Not only do I NOT experience brake fade on long trail rides or racing, but it stopped that annoying rear brake squeak and locking up of the rear wheel while entering corners. With less heat in the rear brake system, I now have increased pad life as well."
