Mach V Subaru Brembo Caliper Replacement Pistons 2017+ BRZ/FR-S/GR86

After hard use or age, your BRZ (or FR-S, or GR86) Brembo brake calipers might need some TLC. Pistons can get gummed up and grit and dirt can end up inside the works. Sometimes the pistons get so badly scored they just need to be replaced.

Fix your caliper up with the help of our aftermarket replacement piston kits. Each kit gives you all the pistons you need to fix ONE caliper. If you need to repair both calipers, get TWO kits. For a full car set, get two front kits and two rear.

As you might already know, BRZ/FR-S/GR86 front Brembo calipers are different from the WRX/STI versions, in that the BRZ variant has equal-sized piston diameters, while the WRX/STI caliper has two different piston sizes.

Our replacement caliper pistons are CNC-machined from super-strong T6061 aluminum, to exactly match the size of the OEM Brembo pistons.

Note that dust boots and piston seals are NOT included in this kit, but they are available to purchase separately here.

We don’t normally split the calipers in half if they are not leaking, but if you do you’ll need replacement O-rings.

Use caution when handling any caliper pistons; you want to take particular care not to damage the outer barrel.

Fits all 2008-2014 Subaru WRX STI, and other cars equipped with black Subaru Brembo STi calipers.
