During routine inspections, we inspect tire tread and pressure, battery health, belts, hoses, brake pad thickness, and engine/cabin air filters to preserve optimal performance and safety standards.

We conduct fluid analysis to monitor oxidation, contamination, and additive depletion in engine oil, coolant, brake fluid, and power steering fluid, then flush or replace based on documented thresholds, not guesswork. We also verify charging output, inspect wiper systems, perform wheel alignments, and torque critical fasteners to spec. With precision tools and documented results, you'll catch small issues early, keep warranties intact, prolong component lifespan, and keep predictable ownership costs.

Engine, Transmission, and Drivetrain Expertise

Even though symptoms can overlap, we pinpoint engine, transmission, and drivetrain issues with analytical diagnostics ahead of physical work. We scan live PIDs, run compression and leak-down tests, validate fuel trims, and evaluate ignition patterns to resolve rough idle, cold starts, or oil dilution from misfires and short trips. You get comprehensive results, repair solutions, and expected outcomes.

Regarding transmissions, we assess line pressure, shift timing, solenoid duty cycles, and fluid condition to prevent slip, flare, or harsh engagements. We recalibrate the TCM/PCM when strategy updates correct drivability issues.

Drivetrain inspections include CV joints, U-joints, differential lash, and wheel bearing noise analysis. We check angles and balance to eradicate vibration under load. You approve every step, and we document findings so you grasp the cause, the correction, and warranty coverage.

Brake, Suspension, and Steering Solutions

As you brake, steer, or drive over a bump, your vehicle should perform as expected—so we initiate our process with detailed brake inspections and focused repairs.

If rotors are within specifications, we complete rotor resurfacing to provide a flat, consistent braking surface; otherwise, we recommend replacement.

We inspect brake fluid for boiling point and moisture, flush systems to remove air, and check ABS operation. You'll receive a clear noise diagnosis for grinding, squeals, or pulsation, focusing on root causes instead of guessing. We also maintain and adjust your parking brake for proper release and secure holds. Anticipate clear estimates, premium parts, and verified results.

Suspension Evaluation and Fine-Tuning

Because ride quality and control begin where the tires meet the road, our suspension diagnostics detect wear and alignment issues before they develop into safety problems. We check ride height, inspect ball joints, bushings, shocks, and struts, and document play, leaks, or binding. You'll get clear findings with priority levels, so you can plan repairs with confidence.

We road-test for noise, impact harshness, and rebound control, then validate spring rates and shock performance with calibrated equipment. If your vehicle permits, we perform damping adjustment to balance comfort and stability, customizing compression and rebound for your load and driving requirements.

Your vehicle will have a suspension that responds predictably, reduces tire wear, and restores control.

Steering, Alignment, and Safety

Accurately aligned steering maintains your vehicle tracking straight, extends the life of tires, and shields critical components. At Master Auto Care, we measure toe, camber, and caster to factory specs, then correct them with precision equipment. If you experience pull, off-center wheel, or irregular tire wear, a complete wheel alignment restores geometry and decreases braking distances by keeping the contact patch ideal.

We thoroughly check steering racks, tie-rod ends, control arms, and bushings for movement that can affect alignment. Our safety checks confirm torque on fasteners, steering more info angle sensor calibration, and tire pressures to guarantee consistent response under load. We conduct test drives to verify accurate center feel and stability at speed. You leave with documented readings, clear recommendations, and a steering system optimized for long-term safety and performance.

Electrical Systems and Advanced Troubleshooting

Although contemporary vehicles are built with increasingly complex electronics, you still require clear, methodical diagnostics when warning lights appear, accessories stop working, or a no-start happens. We begin with a confirmed concern, evaluate battery health and voltage drop, then isolate faults using circuit mapping to trace power and ground paths. We examine fuses, relays, and modules under load, not just visually.

Following this, we attach a scan tool to retrieve live data and stored codes, then verify with oscilloscope waveform analysis. This allows us view sensor signals, injector control, and CAN bus activity in real time, distinguishing intermittent faults from hard failures. We restore corroded connectors, pin-fit issues, and damaged harnesses, then perform a final functional test drive. You leave with restored reliability and confidence.
