Parts for your 2018 Mitsubishi Asx-Brake calipers

2018 Mitsubishi ASX brake calipers — what they do and how to look after them

Based on the Mitsubishi ASX 2018 Owner’s Manual, the Mitsubishi Motors Service Manual (Group 35A – Brakes) for ASX/Outlander Sport, and Mitsubishi Motors Australia MY18 specification sheets, brake calipers are fitted to the 2018 Mitsubishi ASX. All AU/NZ 2018 ASX variants have front ventilated disc brakes with floating calipers, many trims use rear drum brakes, while some markets and grades feature rear disc brakes with calipers. So brake calipers are absolutely relevant to this model.

On the ASX, the brake calipers are the muscle of the disc-brake system. When the driver presses the pedal, hydraulic pressure pushes the caliper pistons, squeezing the pads onto the rotor to slow the car. The sliding pins let the caliper centre itself so pad wear stays even, and the rubber boots and seals keep dust and moisture out.

Up front, those calipers do the bulk of the stopping because the vehicle’s weight shifts forward under brakes. Where rear disc brakes are fitted, smaller calipers assist with balance and stability. Whether front only or front and rear, healthy calipers are key to straight, confident stopping.

• Inspection: At every service or pad change, check for fluid leaks, torn dust boots, seized slide pins, uneven pad wear, and corrosion on the piston faces.
• Servicing: Clean and lubricate slide pins with high-temp brake grease, replace damaged boots and seals, and ensure pads move freely in the bracket. Don’t hang the caliper by its hose.
• Brake fluid: Replace brake fluid every 24 months (per Mitsubishi guidance) and bleed the system properly, use the spec shown in the owner’s manual (typically DOT 3 or DOT 4 as listed).
• Replacement: If a caliper is leaking, badly corroded, or sticking after a proper clean, fit a quality replacement or an approved rebuild kit. Always torque mount bolts to the service manual spec.

Tell-tales of a sticking ASX caliper include pulling to one side, a hot wheel, burning smell after a short drive, poor fuel economy, or pads wearing faster on one side. Sorting it early prevents rotor damage and saves money. For parts selection, match the VIN and build date, noting that AU/NZ 2018 models commonly have front calipers only, with drums at the rear.

Does the 2018 ASX have rear brake calipers?

Most AU/NZ 2018 ASX grades run rear drum brakes (no rear caliper). Some markets or higher trims may have rear discs with calipers. A quick check behind the rear wheel or a VIN-based parts lookup will confirm what’s fitted.

How often should ASX brake calipers be serviced or replaced?

Inspect calipers at every service and whenever pads are replaced. Replace or rebuild if there’s fluid leakage, seized pins, damaged seals, uneven pad wear, or sticking. Change brake fluid every 24 months to protect internal caliper components.

What are the signs of a sticking caliper on an ASX?

Common signs include the car pulling under brakes, one wheel running hot, a burning smell, reduced economy, and tapered or rapid pad wear. If any of these show up, book it in before the rotor and pads cop unnecessary damage.
