What it is
A Mitsubishi Outlander disc brake caliper (also called a brake caliper, caliper assembly, brake clamp, or disc brake cylinder) squeezes the brake pads against the rotor to slow or stop the SUV. It uses hydraulic pressure from the master cylinder to push one or more pistons, clamping the pads on the spinning disc. Modern calipers are either Òfloating/slidingÓ (move side-to-side) or ÒfixedÓ (don't move and use pistons on both sides). (Wikipedia)
Where it fits
Outlander models use front and rear disc brake calipers. Fitment varies by year, trim, drivetrain (2WD/AWD), and whether your vehicle has an electronic parking brake (EPB). Many newer Outlanders and Outlander PHEV models use rear calipers that integrate the parking brake mechanism or an electric motor. Always match by year, engine, axle (front vs. rear), and side (left/driver or right/passenger). For service and part-matching basics, Mitsubishi service literature shows to hang the caliper when removed and never press the brake pedal with the caliper off the rotor. (static.nhtsa.gov)
Safety & recalls
Mitsubishi announced a safety recall on certain 2016 Outlander and 2016 Outlander Sport vehicles to address rear parking-brake caliper issues; the remedy involved replacing the rear brake caliper assemblies. You can quickly check your VIN for any open recalls with the U.S. safety agency. (static.nhtsa.gov, consumerreports.org, NHTSA)
Brake fluid basics
Your calipers rely on clean, correct brake fluid. DOT 3 and DOT 4 fluids must meet federal performance requirements (FMVSS No. 116). Never mix in mineral oils (like gasoline or light oil) or use contaminated fluid-rubber parts can swell and fail. Many Mitsubishi owner and service references allow DOT 3 or DOT 4 (check your cap or manual). (eCFR, NHTSA, static.nhtsa.gov, mitsubishicars.com)
Signs you need one
Watch for these common brake-caliper problem clues: pulling to one side when braking, uneven pad wear, overheating or burning smells, brake drag, vibration, warning lights, or longer stopping distance. These are general brake warning signs from trusted safety and auto organizations. If you notice them, inspect the brakes soon. (aaa.com, cluballiance.aaa.com, acg.aaa.com)
Outlander-specific notes
* Electronic parking brake (EPB): Some Outlanders have EPB rear calipers. For bleeding and pad work on EPB models, follow service steps-some procedures include operating the parking brake multiple times during bleed and using a service Òmaintenance mode.Ó (static.nhtsa.gov)
* Noise fix: Mitsubishi issued a 2024 bulletin for 2022-2024 Outlander and 2023-2024 Outlander PHEV for front caliper noise, prescribing improved pad retainers and rotor inspection. (static.nhtsa.gov)
Replacement tips
* Safety first: Support the caliper; do not hang it from the hose. Do not press the brake pedal with the caliper removed. (static.nhtsa.gov)
* EPB care: For EPB rear calipers, use the proper procedure or a scan tool to enter maintenance/service mode so the piston can retract correctly. (static.nhtsa.gov)
* Cleanliness: Keep dirt and oils out of the hydraulic system; use only fresh, correct brake fluid when cleaning parts like the master cylinder and calipers. (static.nhtsa.gov)
* After the job: Follow proper bleeding order noted in service literature (many models specify a diagonal sequence) and confirm firm pedal feel before driving. (static.nhtsa.gov)
Parts checklist
When choosing a Mitsubishi Outlander brake caliper, double-check:
* Position: Front or rear; left/driver or right/passenger.
* Parking brake style: Standard cable lever vs. electronic parking brake (motor-on-caliper).
* Hardware: With or without bracket; new guide pins, boots, pad clips, and bleeder screw.
* Piston type: Single- or dual-piston front designs depending on model/year.
* Hose fitting: Match the inlet thread style and banjo/flare type for your year.
* Finish & material: Coated/cast-iron or aluminum, depending on application.
(Use your VIN and service references to verify exact fit.)
Bedding-in (break-in)
After installing new front pads/rotors or if pedal feel is soft at very low mileage, Mitsubishi service guidance calls for controlled stops to mate pads to rotors (ÒburnishÓ), with cool-down between runs. Perform only in a safe area and obey traffic laws. (static.nhtsa.gov)
Maintenance schedule
Routine brake checks help keep calipers healthy. Mitsubishi's maintenance schedules include inspecting pads/rotors and replacing brake fluid at set intervals. Follow the schedule for your model year and driving conditions. (mitsubishicars.com)
How it works (simple)
Pressing the brake pedal builds hydraulic pressure. Fluid pushes the caliper piston(s). Pads squeeze the rotor, turning speed into heat and slowing the SUV. Fixed calipers use pistons on both sides; floating calipers slide so one piston can clamp both pads. (Wikipedia, Encyclopedia Britannica)

Frequently Asked Questions
Q: What does the disc brake caliper do on my Outlander?
A: It clamps the brake pads onto the rotor to slow the wheel using hydraulic pressure from the master cylinder. (Wikipedia)
Q: Are there different calipers for front and rear?
A: Yes. Front and rear calipers differ, and many newer Outlanders use special rear calipers that include the parking brake mechanism or an electric motor for EPB. Match by axle and by side. (static.nhtsa.gov)
Q: How do I know if my Outlander has an electronic parking brake (EPB)?
A: Look for a small ÒPÓ button near the shifter instead of a lever. If you have EPB, special steps are needed to service the rear calipers (maintenance mode).
Q: What are signs a caliper is sticking or failing?
A: Pulling to one side, uneven pad wear, heat or burning smells after a short drive, vibration, or longer stops. Have the brakes checked if you notice these. (aaa.com, cluballiance.aaa.com)
Q: Is there a recall for Outlander brake calipers?
A: Certain 2016 Outlander and Outlander Sport vehicles were recalled for rear parking-brake caliper issues. Check your VIN on the official recall site to be sure. (static.nhtsa.gov, NHTSA)
Q: Which brake fluid should I use-DOT 3 or DOT 4?
A: Follow your cap/owner's manual. DOT 3 and DOT 4 must meet federal rules (FMVSS No. 116). Many Mitsubishi references list DOT 3 or DOT 4; DOT 4 has a higher boiling point. (eCFR, Scribd)
Q: Can I clean calipers with regular solvents?
A: No. Don't use mineral oils or gasoline on brake parts-these can damage rubber seals. Use only new, correct brake fluid when cleaning components. (static.nhtsa.gov)
