Parts for your 2017 Mitsubishi Asx-Brake wheel cylinders

2017 Mitsubishi ASX brake wheel cylinders – are they used?

Short answer: brake wheel cylinders aren’t used on the 2017 Mitsubishi ASX sold in Australia and New Zealand. That model runs disc brakes front and rear, so there’s no drum-brake wheel cylinder in the system.

This isn’t guesswork. Technical sources such as the Mitsubishi Motors ASX (GA2W) Workshop Manual (2016–2018) list rear disc brakes with a single-piston floating caliper, not drums with wheel cylinders. OEM parts catalogues (Mitsubishi ASA/EPC) for AU/NZ 2017 ASX variants show rear calipers, pads and rotors but no wheel cylinder part numbers. Major aftermarket catalogues used by local workshops (e.g., Bendix and DBA) list front and rear pads and rotors for the 2017 ASX and likewise do not list a wheel cylinder for this vehicle.

Why no wheel cylinders? Wheel cylinders are a component specific to hydraulic drum brakes. The 2017 ASX uses hydraulic disc brakes on all four corners, where a caliper squeezes pads against a rotor. That setup offers consistent performance and easier servicing. Even the parking brake on many ASX trims is handled via a mechanical “drum-in-hat” handbrake or a caliper-based mechanism, either way, there’s no hydraulic wheel cylinder involved.

What should owners focus on instead? For brake maintenance on a 2017 ASX, think discs and calipers: fresh brake fluid every two years or 40,000 km (whichever comes first), inspect pad thickness and rotor condition, clean and lubricate caliper slide pins, check the condition of brake hoses, and ensure the handbrake mechanism is adjusted and moving freely. If there’s spongy pedal feel, pulling to one side, squeal, or visible fluid around a caliper, book it in—those are the real-world flags on this model. If a 2017 ASX happens to be an unusual market variant with rear drums (rare for AU/NZ), it would be identifiable by a drum backing plate behind the rear wheel rather than a rotor, in that case, a proper parts lookup by VIN will confirm. For mainstream AU/NZ cars though, wheel cylinders simply aren’t part of the picture.

• Key maintenance items: pads, rotors, caliper slides, brake fluid, brake hoses
• Common symptoms to watch: squeal, vibration under braking, uneven pad wear, fluid leaks at calipers

Popular questions

Does the 2017 Mitsubishi ASX have brake wheel cylinders?
No. The 2017 ASX in Australia and New Zealand uses disc brakes front and rear, which means it has brake calipers, not wheel cylinders. Wheel cylinders are only found in drum brake setups.

What replaces the “wheel cylinder” function on a 2017 ASX?
The brake caliper does the hydraulic squeezing on a disc system. On the ASX, keeping calipers sliding freely, pads within spec, rotors smooth, and the brake fluid fresh covers the jobs a wheel cylinder would handle on a drum-brake car.

Could any 2017 ASX variant use wheel cylinders?
In AU/NZ spec, it’s disc rear brakes across the board, so no. In some overseas markets, certain trims of similar models can run rear drums, but that’s not the norm here. If unsure, check for a rotor behind the rear wheel or have the VIN checked against the OEM parts catalogue.
