GeoBrakes stocks complete parking brake shoe kits confirmed to fit the Infiniti Q40 drum-in-hat rear parking brake system, combining OEM-grade parking brake shoes matched to the Q40 drum diameter with the return springs, shoe strut, adjusting screw assembly, and retaining clips needed for a correct, fully functional parking brake service on your Infiniti Q40. Replacing shoes without the hardware is the leading cause of parking brake failure after service on the Q40 in American conditions.
A parking brake shoe kit for the Infiniti Q40 restores complete parking brake function, not just the friction lining. The most common reason a freshly serviced Q40 parking brake fails to hold on a hill is not worn shoes: it is a seized adjuster that prevents the shoe-to-drum clearance from being correctly set after installation on your Infiniti Q40. In the enclosed drum-in-hat cavity of the Q40, road salt and meltwater concentrate corrosion on the adjuster threads, the return springs, and the strut. A kit that includes every hardware component alongside the shoes is the only way to guarantee the Infiniti Q40 parking brake performs correctly after service.
The kit for your Infiniti Q40 includes parking brake shoes with OEM-grade friction lining at the correct arc length and lining width for the Q40 drum-in-hat diameter, return springs that retract both shoes cleanly after the Q40 parking brake is released, hold-down hardware with springs and pins that locate the shoes while permitting actuation on your Infiniti Q40, the parking brake strut connecting both shoes through the Q40 mechanism, the adjusting screw assembly setting correct shoe-to-drum clearance for reliable holding force on your Infiniti Q40, and retaining clips and washers securing the strut and adjuster in correct operating position on the Q40.
The parking brake shoe adjuster on the Infiniti Q40 sets the gap between the shoes and the inner drum surface of the Q40 rotor hat. In American winters, the drum-in-hat cavity of the Q40 traps road salt and moisture. The adjuster threads on your Infiniti Q40 corrode and seize, sometimes within a single winter season. A seized adjuster on the Q40 produces a parking brake that either drags against the drum when released or fails to hold the Infiniti Q40 on a slope when engaged.
Parking brake shoe kits for the Infiniti Q40 are among the most vehicle-specific brake components in the catalogue. The shoe arc length, lining width, spring rates, strut length, and adjuster thread specification for the Q40 are all determined by the specific drum-in-hat diameter of the Infiniti Q40 rotor. Every kit in the GeoBrakes catalogue is assembled for the Infiniti Q40 exact year and model, with zinc-plated or coated hardware components to resist the concentrated corrosion inside the Q40 drum-in-hat cavity.
How do I know if my Infiniti Q40 uses parking brake shoes?
Infiniti Q40 vehicles with four-wheel disc brakes often use a drum-in-hat parking brake requiring separate shoes. Some Q40 variants instead use a caliper-actuated parking brake. Use the GeoBrakes vehicle selector to confirm your Infiniti Q40 parking brake type and find the correct kit.
My Infiniti Q40 parking brake light stays on after I release it, do the shoes need replacing?
A warning light that stays on after full release on the Infiniti Q40 can indicate worn shoes, a faulty sensor, low brake fluid, or a stretched cable on the Q40. If the Infiniti Q40 fails to hold on a slope, a shoe kit replacement combined with cable and adjuster inspection is the recommended starting point for your Q40.
Can I adjust the parking brake on my Infiniti Q40 after installing a shoe kit without replacing the cable?
Yes, if the Q40 cable is in good condition and within its adjustment range. After correct shoe installation and adjuster setting on the Infiniti Q40, adjust the cable until the brake holds firmly within three to five clicks of Q40 lever travel.
