Replacement aluminium piston complete with seals.
Fits various models of hydraulic rim brake levers.

- CNC machined aluminium piston to fit various models of hydraulic rim brake lever (not slave cylinders).
- Being made from aluminium means the brake can be water-bled with no "swelling" issues, as found with nylon pistons.
- Features twin O-rings rather than the usual O-ring and dust seal combination.
- Available in anodised red or black.
- Fitment with a light smearing of silicone grease on the seal is recommended. Please note that other greases and lubricants can cause the rubber seal to deform.
- Available with 13mm or 14mm diameter (sizing refers to the diameter of the main body of the piston) - please check your existing brake to compare before ordering.
- Sold singly.
- A standard Magura spring does not fit over the lip on this piston, we can machine it down for you from 9.3mm to 8.5mm if you add this product to your basket too: Racing Line Piston Machining.
- Weight: 4.5g

Please note: These pistons will not work with 2004 (or earlier) Magura HS11 brakes with a 16mm piston.

Echo TR lever leaking solved

Posted by Antonio

Got the same known problem with Echo TR disc brake lever leaking. The original plastic piston wasn't sealing, and after only 6 months of use. The Racing Line piston solved the problem. Perfectly fit the lever, no more leaking and the same smoothness. Thank you guys from Tarty.

Very good.

A bit of a task fitting and adjusting this but once fitted and used alongside a Racing Line TPA kit provides a firmer and more comfortable feeling. The double seals are more than enough to prevent fluid leaking under pressure and the alloy won't suffer the same stress as Maguras standard plastic piston (mine cracked hence the replacement).

Hi Andy - thanks for your review, and we're glad you're happy with your purchase. From our experience, the brake will likely feel firmer because of the fresh bleed rather than the piston itself. Thanks again, Flipp.
