Full description of the product (H1: Brake caliper repair kit B-I32x2 - Group Birel Art / Freeline)

The repair Kit for Brake Caliper B-I32X2 is a repackaging set of origin manufacturer (Original Freeline / Birel Art). It is essential to revise and give all its biting to the rear braking system of the group's competition chassis Birel ART equipped with the B-I32x2 reference bracket (generally used on adult categories such as Rotax, X30, ok and kz).

Subject to immense thermal stresses (the rear discs that can rise to more than 400 ° C in the race), the internal seals of a caliper end up cooking, drying up and lose their elasticity with time. This complete kit makes it possible to replace all the sealing elements to remove the brake fluid leaks, guarantee a quick return of the pistons in their housing and avoid the piston piston phenomenon that make the platelets rub in straight line.

Composition of the repair kit:

The sealed bag includes all seals specific to the B-I32x2 model (diameter adapted to 32 mm pistons):

• Main seal joints (High pressure internal cups).

• The dustproof joints outside.

• The O-rings binding joints (for tightness between the two half-shells of the stirrup).

• Chassis compatibility: Birel Art, CL Kart (Charles Leclerc), Ricciardo Kart, Kubica, LGK.

- 3. Tip in Michel (the corner of the expert)

* "Hi late braking trappers! Tackle the refurbishment of a B-I32x2 caliper, it is the most important maintenance operation for your track safety. When the pedal starts to become spongy or your platelets lecheck the disk to The stop, do not look for noon at fourteen o'clock: your joints are cooked !

My trick of old mechanic for a surgical reassembly: banis absolutely the screwdrivers or metal tools sharp to house your new seals. If you make a micro-scratch in the aluminum of the caliper or if you are entering a joint lip with an iron tool, your caliper will flee from the first big pressure on the pedal. Use plastic tools or your fingers.

Before inserting the new joints and the 32 mm pistons in their bores, lubricate them generously with clean brake fluid (DOT 4 or DOT 5.1) or a special grease for brake seals (lithium red fat). Do not go up dry! The pistons must slide firmly but fluid by hand. Once reassembled, make a careful purge, and you will find the pedal attack of a factory chassis! "*

❓ 5. FAQ SEO (Frequently Asked Questions)

Q: Is this kit compatible with the front brake calipers KARTS KZ Birel Art ?

A: Not. KZ front calipers usually use pistons of lower diameter (often from 22 mm or 24 mm). This kit is specifically calibrated for the large rear caliper model B-i32x2 equipped with pistons of 32 mm.

Q: How often does the joints of its brake caliper replace ?

A: In high level competition, it is recommended to make a complete refurbishment of the caliper at least once per season or as soon as you see a baking liquid oozing around the pistons, or if the pistons have trouble returning to the initial position after a big braking.

Q: Does this kit also include steel / aluminum pistons ?

A: Not. This original kit includes only the set of rubber / elastomer seals (cups, dust and inter-shell-cozy). If your 32 mm pistons are highly scratched or marked, they must be ordered separately.
