    BMW E82 Caliper Rebuild Kits

    Brake caliper piston seals are there to maintain brake system pressure and prevent fluid from leaking out from inside the caliper. When a seal goes bad or becomes damaged the brakes lose pressure, leading to a soft brake pedal, sticking caliper, or even a total loss of your brakes. Brake calipers also need periodic rebuilds because the inner piston can seize from rust. With a piston stuck in the retracted position, the brakes are no longer functioning on that wheel. If the caliper is stuck in the extended position it's putting clamping force on your brakes - dragging the brakes, front wheel vibrations, pulling to one side, excessive brake dust and heat, and potentially even a brake pad fire. For cars that see significant track use, regular caliper rebuilds are essential because higher temps lead to rubber seal failures sooner.

    Rebuilding your calipers should be part of a regular brake overhaul. The calipers must be removed from the car and disassembled. It's not a particularly difficult job to do but is messy and takes some expertise so that you don't ruin the piston or new seals. Rebuilding calipers is more cost effective than buying replacement calipers. However you service the calipers don't prolong their maintenance until it's too late!

    A set of dust boots to rebuild the 6-piston Brembo front calipers on the E82/E88 135i. This is also the correct seal kit to rebuild the BMW 6-piston Performance calipers fitted as an upgrade to many BMW models. One kit is enough for one caliper.

    This item fits the following BMWs:
    2008+ E82 BMW 135i
    Any other BMW model that has been upgraded with the BMW 6-piston Performance Brake kit.
    Part #: 34116780507

    The Brembo 6-piston brakes on the 135i promised a major step forward in BMW braking performance. But if you have driven or tracked your 135i hard you have probably found that the calipers are not impervious to issues. While great on the street, numerous owners have reported problems from the track. First and foremost, the caliper pistons have a ceramic buffer between the piston and the brake pad which can easily deteriorate and crumble under the extreme heat from race pads and the track. BMW will sell replacement seals but not the pistons separately.

    This set of aluminum pistons and seals are from the StopTech line of calipers and are a direct replacement for the Brembo pistons in the 135i. If you want an upgrade to seals and pistons with greater durability than the originals, this is your ideal kit. StopTech has been the official brake supplier for our racing team since 2003, ensuring that these parts will stand up to the harshest track environments (periodic seal replacement and rebuilding still recommended). For greater braking performance you should also run brake cooling ducts and higher temp brake fluid.

    Price is for a full set with enough pistons and seals to do both front calipers. If you have already done this upgrade and just need the seals, choose that option below.

    This item fits the following BMWs:
    2008+ E82 BMW 135i
    Any other BMW model that has been upgraded with the BMW Performance Brake kit.
