Here at M&R Auto, we have proudly kept Atherton area Acura owners safely and confidently on the road for years with our auto shop located in nearby Menlo Park. In that time, we’ve seen countless Acura vehicles come through our doors spanning models like the NSX sports car, best-selling MDX SUV, midsize TLX sedan, through to the flagship RLX luxury sedan. While each Acura model features slightly different brake system specifications and components, they share common traits of being over-engineered to perform and built to last.
That said, brakes remain wear items exposed to constant heat cycling, moisture, and physical forces that take a toll over the years. In this comprehensive guide, we’ll break down the most common Acura brake problems owners experience along with expert recommended solutions. From brake rotor resurfacing to ABS module diagnostics and everything in between, read on to ensure your Acura continues stopping smoothly for years to come.
Eliminating Annoying Brake Pedal Pulsation
One of the most common complaints we address for Acura owners relates to an unsettling vibration or pulsating sensation felt through the brake pedal when slowing down. Typically noticed when braking at higher speeds, this issue stems from warped brake rotors that develop thickness variations across the braking surface. The cause relates to the extreme heat brake rotors endure during heavy or repeated braking scenarios.
Over time, areas of a rotor can overheat and become thinner relative to cooler sections, creating a “warped” effect. As the brake pads clamp down during braking, they transfer these thickness inconsistencies into pedal pulsations drivers can feel. If left alone long enough, rotor warping can accelerate pad wear and reduce braking performance through uneven contact across the rotor’s surface.
M&R Auto’s step-by-step process for eliminating brake pedal pulsation:
- High accuracy rotor thickness measurement to check for warping
- On-car brake rotor resurfacing to restore uniform thickness
- Rotor replacement if beyond resurfacing specifications
- Install new OEM-grade brake pads for proper mating surface
- Caliper inspection to check pad/rotor alignment under clamping pressure
- Confirm resolution after road testing vehicle
Be proactive by having brake rotors periodically measured for thickness consistency during routine service. Address any perceived pulsation right away to maximize rotor resurfacing opportunities over outright replacement. Sticking to manufacturer recommended brake pad replacement intervals also ensures optimal mating between pads and rotors.
Silencing Annoying Brake Squeal
While some brake noise falls within acceptable levels, especially for high performance models like Acura’s Type S variants, persistent squealing when braking becomes an annoyance owners want resolved. The root causes can vary from glazed brake pads and rotors failing to make full contact, lack of anti-squeal shims on pad backings, or high-friction performance pad compounds used in sports models. Vibration between the pad and rotor surface creates the squealing noise drivers hear.
M&R Auto pinpoints the source through:
- Thorough brake component inspection checking pad thickness and rotor condition
- Comparing hardware like shims against factory spec
- Cleaning and lubricating abutment points to alter vibration frequency
- Pad and rotor replacement if glazing or uneven deposits found
- Road testing to confirm noise elimination
While some brake noise is unavoidable in spirited driving conditions, having worn pads or rotors promptly replaced reduces the likelihood of irritating squeal developing during normal around town driving.
Firm Brake Pedal Feel for Confident Stopping
Over their lifespan, Acuras may develop issues leading to a low, spongy brake pedal that fails to inspire stopping confidence expected from the brand. This stems from air ingestion into the hydraulic system, leaks, or components like master cylinders and ABS pump units wearing internally over time. Drivers sense a pedal that drops away under foot pressure rather than remaining firm and responsive.
Utilizing both visual inspection and electronic diagnostic testing allows our technicians to accurately pinpoint issues like fluid leaks or internal failures prompting the spongy pedal. From there, we methodically restore system integrity through:
- Brake pedal firmness test checking vacuum assist
- Hydraulic system bleed to remove any trapped air
- Master cylinder replacement if worn or leaking internally
- Inspecting brake lines and hoses for swelling or leaks
- Confirming ABS module and pump functioning properly
- Final test drive to verify pedal feel to our standards
By having your Acura’s brake fluid flushed and inspected for contamination at factory specified intervals, many issues leading to soft pedal feel can be avoided entirely. Any perceived change warrants prompt diagnosis before accelerated wear damages additional components.
Freeing Up Dragging Brakes
An issue we occasionally see in models equipped with electronic parking brakes relates to brakes failing to fully retract after being applied. This leaves caliper pistons partially extended against the rotor, accelerating wear, and creating noticeable drag felt when accelerating. Potential root causes include seized pistons within calipers, lack of lubrication allowing slides and hardware to corrode, or glazed pads sticking to rotors instead of freely sliding as designed.
Our step-by-step brake service process targets dragging brakes through:
- Visual inspection of pads, rotors, and caliper hardware for sticking points
- Verifying electronic parking brake fully disengages
- Cleaning and lubricating abutment points between pads, caliper, and anchor
- Checking piston freedom of movement within each caliper
- Replacing any damaged or worn components
- Road testing to confirm issue resolution
By having your Acura’s brake system periodically inspected and lubricated, issues like dragging brakes can be prevented entirely. Bring your vehicle in promptly if symptoms arise to reduce costs by servicing components early instead of complete brake replacement being required.
ABS System Assessment and Repair
The advanced ABS systems equipped on all Acura models provide an extra level of control and safety when braking in compromised conditions. However, like all complex electronic systems, gradual issues can develop over time including sensor failures, wiring damage, or internal hydraulic defects. Warning lights indicating a fault often prompt owners to schedule service, but even intermittent problems warrant diagnosis to prevent future complications.
Our brake specialists leverage factory-grade diagnostic tools and training to accurately assess ABS faults. This allows us to zone in on the root cause whether it stems from a bad wheel speed sensor, faulty internal valve operation, or even software bugs requiring an update. We then make precision repairs, bleeding the entire system to ensure proper operation. This comprehensive approach helps prevent comebacks and gives owners confidence in their Acura’s braking capabilities across all traction conditions for optimal safety.
