ABS 722021 Rear Left Brake Caliper

Replacement ABS rear left brake caliper for Mazda MX-5 MK3, MK3.5 and MK3.75 / NC 1.8 and 2.0 models listed in the compatibility table.

The brake caliper uses hydraulic pressure to clamp the brake pads against the rear brake disc when the brake pedal is applied, providing the braking force required to slow the vehicle. This rear caliper also incorporates the mechanical parking-brake mechanism and is designed as an aftermarket replacement for the original component.

ABS 722021 is fitted to the rear left side of the vehicle. One caliper is used on this side, with ABS 722022 being the corresponding rear right caliper.

Rear brake calipers are commonly replaced because of a seized or slow-moving piston, sticking slider mechanism, corrosion, hydraulic fluid leakage or a sticking handbrake mechanism. Typical symptoms can include uneven rear pad wear, excessive brake drag, poor handbrake operation, reduced braking efficiency or the vehicle pulling under braking.
