Parts for your 2015 Mitsubishi Asx-Brake calipers

2015 Mitsubishi ASX brake calipers: what they do and how to look after them

Technical sources confirm the 2015 Mitsubishi ASX is fitted with brake calipers. Mitsubishi Motors’ Service Manual (Group 35A – Brakes) for ASX/RVR/Outlander Sport MY2010–2016 specifies ventilated front disc brakes with sliding single‑piston calipers, while the rear is variant‑dependent (solid disc with a caliper or a drum set‑up). Autodata specifications, the Mitsubishi ASA parts catalogue, and major brake catalogues (e.g., Bendix and DBA) also list front caliper assemblies and pad kits for the 2015 ASX. So, brake calipers are very much relevant on this model.

On the ASX, the caliper’s job is to clamp the pads onto the rotor to slow the car. Each caliper houses a piston, seals and slide pins that must move freely and stay well‑sealed. Up front they handle most of the stopping work, so they cop heat, grit and spray—particularly in Aussie and Kiwi conditions.

Good servicing keeps calipers smooth and safe:

• Inspect at every service and whenever pads/rotors are replaced. Look for torn boots, leakage, uneven pad wear and sticky slide pins.
• Clean and lubricate slide pins with a proper high‑temp silicone/synthetic caliper grease, renew pin boots if perished.
• Replace pad abutment clips/shims with quality parts, ensure pads slide freely in the bracket.
• Flush brake fluid every 2 years or about 40,000 km (use the fluid specified on the reservoir cap—commonly DOT 3 or DOT 4), bleed thoroughly after any caliper work.
• Torque caliper bracket and guide pin bolts to spec and use new copper washers on banjo fittings where applicable.

Replace a caliper if the piston is seized, the bore is pitted, boots are torn with water ingress, or there’s persistent uneven pad wear. Rebuild kits can work if the bore is clean and true, but many owners opt for quality reman or new units to save time. Always service both sides of an axle together, and check the rotor thickness and runout at the same time. For ASX variants with rear disc brakes, the caliper handles service braking only, with a separate drum‑in‑hat park brake, drum‑brake cars don’t have rear calipers, so the front calipers are still the main focus.

Common signs it’s time to act include a pull to one side under braking, a hot wheel after a short drive, squeal or grinding returning after new pads, or visible fluid around the caliper. Sorting issues early keeps pedal feel crisp and stopping distances short.

Popular questions

How often should ASX brake calipers be serviced?
They should be inspected at every service and properly cleaned and lubricated whenever pads or rotors are changed, or at least every 20,000–40,000 km. In harsher conditions (beach driving, gravel, snow), shorten the interval.

Can a seized caliper on a 2015 ASX be rebuilt?
Yes—if the piston and bore aren’t corroded or scored. A quality seal kit, new boots and fresh slide hardware can restore function. If corrosion is heavy or the piston is pitted, replacement is the smarter, longer‑term fix.

Does the 2015 ASX have rear discs or drums?
Both were offered depending on variant and market. Many Australian and New Zealand models feature rear discs with a drum‑in‑hat park brake, while some trims use rear drums. Front calipers are fitted across all variants.
