Parts for your 2021 Mitsubishi Asx-Brake shoes

2021 Mitsubishi ASX brake shoes — what they do and when to service them

Brake shoes are relevant to the 2021 Mitsubishi ASX in Australia and New Zealand. Technical references including the Mitsubishi Motors Australia 2021 ASX Specification Guide, the ASX Owner’s Manual, and the Mitsubishi Service Manual (Group 35A – Brakes) list rear leading/trailing drum brakes on many 2021 ASX variants (such as ES, LS and MR), which use brake shoes. Some higher-spec variants may have rear disc brakes, in which case they don’t use shoes. For vehicles fitted with rear drums, brake shoes are a normal wear item and part of routine servicing.

On ASX models fitted with rear drums, the brake shoes sit inside the rear drum and press outward against its inner surface to slow the car. They also do double duty for the handbrake/parking brake, holding the vehicle securely when parked. Because they’re enclosed, shoes tend to be well protected from road grime, but they still wear down over time and can glaze or collect dust, which reduces braking performance and handbrake bite.

During regular servicing, a technician will remove the rear drums to inspect shoe lining thickness, look for heat spots or cracking, check the wheel cylinders for leaks, and ensure the self-adjusters and springs are clean and moving freely. As a guide, shoes should be replaced when the friction lining is close to the service limit noted in the workshop manual, or if they’re contaminated with brake fluid or gear oil. Many owners find inspection every 10,000–15,000 km (or at each scheduled service) keeps the rear brakes in good nick and avoids handbrake issues.

If replacement is needed, it’s best practice to replace shoes as an axle set (both sides), machine or replace the drums if they’re out of spec, and lubricate the shoe contact points and adjusters with the correct high-temp brake grease. After new shoes are fitted, bedding-in with a series of gentle stops helps seat the linings to the drum. Drivers should also get the handbrake adjustment checked so the lever travel feels consistent without dragging. Keeping the rear brakes clean inside—blowing out excess dust and checking for corrosion—goes a long way to quiet, consistent braking and a firm, reliable handbrake feel on the ASX.

• Watch for symptoms: longer stopping distances, rear-end squeal or scraping, weak handbrake, pulsation, or a soft pedal.
• Avoid harsh hose-downs around the rear hubs, moisture inside the drum can promote corrosion and noise.
• If towing or frequently driving hilly routes, consider more frequent inspections.

Does the 2021 Mitsubishi ASX have brake shoes?

Many 2021 ASX variants sold in Australia and New Zealand are fitted with rear drum brakes that use brake shoes (e.g., ES, LS and MR). Some higher trims may have rear discs instead, which don’t use shoes. A quick look at the build plate/spec sheet or a peek through the rear wheel will confirm what’s fitted.

How often should ASX brake shoes be replaced?

There’s no fixed kilometre figure because it depends on driving style and conditions. Have them inspected at each service, replace when the lining nears the service limit, if they’re glazed, cracked, or contaminated, or if the handbrake performance drops. Many vehicles see replacement anywhere from 50,000–120,000 km, but earlier if driven heavily or in hilly areas.

What are the signs the ASX’s brake shoes need attention?

Tell-tales include rear-end squeal or grinding, weak or high-travel handbrake, longer stopping distances, a pulsing pedal, or visible fluid around the backing plate (possible wheel cylinder leak). If any of these crop up, book an inspection before daily driving or towing.
