Parts for your 2017 Mitsubishi Lancer-Brake wheel cylinders

2017 Mitsubishi Lancer — Brake Wheel Cylinders

Based on Mitsubishi’s 2017 Lancer workshop manual (Group 35 – Brake), the factory EPC (Mitsubishi ASA), and dealer spec sheets for the CJ-series Lancer, brake wheel cylinders are relevant to models fitted with rear drum brakes. Entry-level trims commonly shipped with rear drums that use a hydraulic wheel cylinder on each side, higher-grade variants feature rear disc brakes and therefore don’t use wheel cylinders. Independent parts catalogues for 2017 Lancer models also list rear wheel cylinders specifically for drum-brake trims, further confirming fitment.

For 2017 Lancers equipped with rear drum brakes, the wheel cylinder’s job is simple and vital: it converts brake fluid pressure into mechanical movement to push the brake shoes against the drum. That’s what slows the rear wheels under normal braking and during handbrake balance adjustments. Because they live inside a dusty, high-heat area and handle corrosive brake fluid, wheel cylinders deserve routine inspection as part of regular servicing.

When replacing wheel cylinders, it makes sense to do them in pairs across the rear axle to keep braking even. If a cylinder has leaked, the brake shoes are usually contaminated and should be replaced at the same time. After any cylinder or shoe replacement, bleed the rear brakes to remove air, check that the self-adjusters move freely, and set the handbrake so it holds well without dragging. Always use the brake fluid grade shown on the reservoir cap/owner’s manual, and never mix incompatible fluid types.

• Common signs they’re due: a soft or sinking pedal, rear-end pulling under braking, fluid weeping behind the backing plate, damp brake dust inside the drum, or uneven shoe wear.
• Good maintenance habits: inspect boots and ends for moisture at every brake service, clean out drum assemblies, and flush brake fluid at the interval in the maintenance schedule (often around 24 months in local conditions).

A tidy drum assembly with healthy wheel cylinders gives a firm, predictable pedal and helps the ABS and stability systems do their job. On a high-kilometre Lancer, minor seepage can become a sudden leak, so catching it early saves the shoes and reduces stopping distances. When fitting new cylinders, choose reputable brands with the correct bore size for the specific trim code, torque the fasteners correctly, and protect paintwork from brake fluid. If the car has rear discs (no wheel cylinders), focus your efforts on calliper slide lubrication, pad wear and fluid health instead.

Popular questions about 2017 Mitsubishi Lancer brake wheel cylinders

Do all 2017 Mitsubishi Lancers have rear wheel cylinders?
Not all of them. Trims with rear drum brakes use wheel cylinders, while models with rear disc brakes don’t. A quick check through the rear wheel: if there’s a drum, it’ll have a wheel cylinder, if you see a calliper and rotor, there isn’t one.

How can someone tell a wheel cylinder is failing on a 2017 Lancer?
Look for dampness or fluid trails at the bottom of the drum/backing plate, a soft or spongy pedal, the car pulling to one side when braking, or contaminated brake shoes. Removing the drum for a proper inspection during a service is the sure way to confirm it.

When should wheel cylinders be replaced on this model?
There’s no fixed kilometre count—replace them whenever there’s leakage, sticking pistons, torn boots, pitted bores or uneven braking. Inspect them at every brake shoe service, and keep on top of brake fluid changes to slow internal corrosion.
