Go to the upper level of deceleration with this elite rear braking assembly, combining italian's precision engineering and the thermal expertise of disks A & a. Designed specifically for the requirements of high-level karting (category 1 and 2 groups), this duet has an official approval CIK / FIA to guarantee you optimal performance in competition.
🛑 The rear caliper Discapciati Ma20 (black anodized)
The Axial MA20 caliper is a mechanical work of art. Fully carved in the mass from forged aluminum blocks and then machined by digital control (CNC), it undergoes strict three-dimensional control in the laboratory. Its structure, outcome of pushed CAD studies, offers an exceptional weight / rigidity ratio (only 920 g) and an outstanding thermal dissipation.
It integrates a double piston of 32 mm with hard anodic oxidation treatment and precision grinding, coupled to an internal dust cover and a system of automatic recovery of platelet wear.

💿 The R & R floating ventilated brake disc (Ref: K239-18-195-FLOW)
To fully exploit the power of the MA20 caliper, this pack includes the brake disc in high performance cast iron produced by R & R. Recognized for its extreme longevity, this disc offers braking of a colossal power without ever sacrificing progressivity or the modulation to the pedal. Its truly floating design allows it to expand freely under the effect of calories, eliminating any risk of thermal sail. Its specific surface strips continually revive the platelet filling and accelerate cooling.

👨🔧. The Tip in Michel (the corner of the expert)
* "Hi the trappers! There, we do not laugh, we are on world championship level material. The discapciati mA20 bracket combo and R & R casting disc, it is the absolute weapon to freeze the landscape at the end of straight line without blocking the Rear Wheels Like a beginner. The cast iron is the king material for braking, but it requires a real mechanic interview.
My obligatory trick for this advanced system: the absolute care of the cast iron and the brooding of the platelets !
First rule: pure cast iron, it rusts with the slightest moisture! If you wash your water jet kart at the end of the day or ride in the rain, the disc will turn into orange in a few hours. It's normal, it's surface oxidation. Do not highlight dripping or oil on it! At the first braking of the next session, the film will leave. My tip: Pass a dry cloth after each wash and apply brake cleaner only on the friction surface before mounting your pads.
Second rule: MA20 has a super precise automatic wafer game catch-up system. When you change the pads, meticulously clean the flank of 32 mm pistons before repelling them. If font dust returns under the internal joints, the catch-up will gripper and your brakes will remain tight in a straight line. A clean system, it's km / h more at the end of the straight line! "*
📐. Mounting guide and alignment: step by step
1.Montage r & R floating disc:10 min.Put the kart on trolley and dismount the left rear wheel. Slide the adapted disk holder (114 mm interravement) onto the shaft. Attach the 195 mm R & R disc to the 6-hole support using new screws and medium net brake. Make sure the disc retains its floating freedom of movement.
2.Installation caliper Ma20:10 min.Attach the Discapciati Ma20 bracket to the brake turntable of your chassis (80 mm spacing). Do not block the screws immediately. Adjust the side position of the caliper with wedding washers so that the 18 mm thick disc is perfectly centered in the middle of the opening of the caliper.
3.Raccordement and fluid:10 min.Connect your original brake hose to the caliper by replacing the Banjo Copper Seals. Fill the master cylinder with high performance brake fluid (DOT 4 or DOT 5.1 according to recommendations).
4. Surgical position and verification:10 min.Purge the circuit for hunting all air bubbles until the brake pedal is firm and without any spongy sensation. Thanks to the automatic wear recovery of 32 mm pistons, operate the pedal several times to stop the pads. Check by hand that the back shaft rotates without excessive resistance.
❓ 5. FAQ SEO (Frequently Asked Questions)
Q: Is this brake set compatible with all Karting chassis marks ?
A: The MA20 caliper uses a standard fixing wheelbase of 80 mm, which makes it compatible with the vast majority of modern rear brake turners. The R & R disk requires a 6-hole disc holder with a center distance 114 mm (available separately for 50 mm trees). Check the available space on your chassis to accommodate the 195 mm diameter.
Q: Why prefer a cast iron disk rather than a classic steel disc ?
A: The font offers a much higher friction coefficient than steel, providing a much higher initial "bite" and better modulation (dosage). In addition, combined with the 18mm thick R & R ventilated design, it dissipates the heat much faster, avoiding that the system does overheat during repeated braking in category 125 box (KZ).
Q: How does the automatic wear recovery of wear on the MA20 caliper ?
A: This system uses specific internal piston joints (quadrings). When the pads wear out and thin, the pistons progressively advance and remain calibrated at the perfect distance of the disc. This ensures that the race of your brake pedal remains rigorously identical from the beginning to the end of the race, without the need for manual adjustment.
