the other radial calipers. The removal of the serial number will invalid warranty and maintenance.

Maintenance on the Accossato caliper is carried out within a working week from the arrival of the radial

caliper. Maintenance includes:

- Visual external inspection of the product

- Dismantling of the parts of the caliper

- Visual microscope inspection of all the components of the caliper

- Visual inspection inside the body of the caliper

- Replacement of the seal dusts

- Assembly of all the parts

- Static test of the caliper

- Dynamic test of the caliper

The replaced parts are disposed and from the maintenance, the caliper acquires a 12-month warranty as

stated by invoice. A further (second) maintenance will not extent the 12-month warranty of the product.

The maintenance will not include replacement of other non-mentioned external parts.

In case of falling, the maintenance is carried out only if the caliper can be fixed and come back to its original

status, like a brand-new part.

F.A.Q.

What to do in case of fall?

The radial brake caliper is a safety product. Accossato discourages to keep on riding after a fall, especially when you suspect or experience issues on its correct functioning.

Is there any repair kit for the Accossato caliper?

Replacements can be purchased separately. Please note that in case of non-original parts mounted on the caliper, the product will not be covered by warranty.

What brake fluid should I use?

Accossato suggests using DOT 4 Accossato Racing fluid, specially conceived to be used by the most demanding clients who desire a top performance braking process. Accossato developers recommend extreme caution when using braking fluids available on the market. More specifically, take extra care when using DOT 5.1 at boiling point: in fact, this fluid must be removed from the braking system soon after a competition and/or a single use. In case you fail to remove it, it may damage the seals of the braking system.

How much should I fasten the bleeding valve?

Accossato recommends to fasten the screw with a torque wrench at 8-10Nm. We discourage to try to fasten the screw with your hands without measuring the tightening. After bleeding the caliper and tight the valve, blow some compressed air around the screw in order to let the oil out that may be left in the crest of the thread and in the central whole with a diameter of 3mm.
