Hydraulic Caliper Piston Seal Repair Kit

Hydraulic Caliper Piston Seal Repair Kit

If you are doing maintenance on your caliper brakes and need to replace your piston, then you’ll likely need to replace your caliper piston seals.

This hydraulic piston seal repair kit suits both AL-KO and Trojan hydraulic calipers. The leading cause of piston failure often stems from worn seals. When a seal is slightly damaged, water can enter the hydraulic chamber, leading to the piston jamming.

How often should you replace your piston seals? Experts recommend replacing your boat trailer caliper piston seals twice a year.

Product Specifications

When you purchase a hydraulic caliper piston seal repair kit, you’ll receive:

• 1 x Piston Seal
• 1 x Piston Ring
• 2 x Caliper Pin Boots

Caliper seals are not easy to install, so patience is required. Once you have installed the first one, the remaining seal inserts will proceed faster.

Clean the piston’s bore before insertion. To help the new piston slide into position, use silicone grease inside the bore.
