Brand:Shimano

Do you have a leaking lever when trying to bleed your Shimano Hydraulic Road Brakes?

We've seen this issue a few times, it happens after the diaphram has burst, which causes the leaking and the lever never bleeds to full power after this.

After speaking to Shimano, we've found out this, in most instances, is not warranty and the levers need to be replaced.
To prevent unneccesary replacement of STI levers, we have managed to get some of the diaphrams needed to save the brake system.

Compatible with;
Shimano Tiagra ST-4720
Shimano 105 ST-R7020
Shimano Ultegra ST-R8020
Shimano Dura-Ace ST-R9020
