Replacement Piston

Not sure I would call this a service kit as it only consists of the piston and o-ring. Other O-rings used on the caliper are not included. The plunger seems to be working as it should. Make sure you order 2 calipers for the price of 1 as they have a piston on each side.

Pros
  • Good product for the price
Cons
  • Long delivery time

ideal function.

Shimano M7000 caliper installation. It is an excellent repuesto to obtain Porsches dañados de shimano, the kit includes 01 pistons and 01 retén, solo installation and vuelve a purgar, el freno funcionará como nuevo. No compres support nuevo, most reparalo con este kit.

Pros
  • Hands-free operation
Cons
  • Useless functions

A quality solution to a caliper piston leak!

The thought of throwing out leaking Shimano M666 SLX calipers didn't make me happy. They are easy to assemble and new seals ensure leak-free operation. You must order 2 to complete the caliper rebuild. Works on par with the original pistons!

Pros
  • Fits me great
Cons
  • Slightly cracked

Great replacement that OEM doesn't have.

Since Shimano doesn't sell parts for their calipers, this is the only option should their pistons burst. Excellent goods. Works perfectly. I would say they actually perform better than the original ceramic pistons. Ease of installation.

Pros
  • Great overall performance
Cons
  • Protection

I used the old seal, the new one doesn't work.

I bought this for my Shimano XTR M9020 front brake and on the seller's recommendation I used the lock that came with the piston and it didn't work, didn't move or disengage. I put the old one back which was original and it worked perfectly. The seal that comes with this piston is tighter than the Shimano XTR.

Pros
  • Sleek design
Cons
  • Some minor issues

Better than Shimano ceramic!

Wow what a great solution to a problem with my XT M8000 calipers. Shimano uses ceramic for the caliper piston and sometimes they like to crackle. Shimano doesn't really sell parts either, and that's where I just ended up with my fat bike. I just installed them in the caliper and reinstalled the caliper on the bike. Pumped as always and boom! We're back in business and tomorrow we're going for a fat bike ride in the snow :)

Pros
  • New
Cons
  • Not bad
