Brakes are the most important safety device on your car. Inspecting your brakes twice a year for wear and damage can protect you and your passengers. Check your brakes periodically will also help save you money by catching any damage before it becomes too costly.


Brake System Components That Can Fail

  • The master cylinder, which is like the heart of the braking system, holds the brake fluid when it is not being delivered to the brakes through the brake lines. If the master cylinder is worn or the brake lines are plugged/broken, the brake fluid will leak and cannot be delivered.

  • The brake fluid itself can become dirty or contaminated as it picks up rust-causing moisture and other debris. Clean brake fluid is either clear or slightly yellow, while dirty brake fluid may be brown or even black. Old or dirty brake fluid can damage ABS brake systems internally.

  • Brake pads and shoes can be made of ceramic, metal, or organic materials, while the disc rotors and drums they press against are made of metal. Because the pads and shoes create friction to stop the car, they gradually wear down over time and may wear away completely, letting the metal of the calipers and cylinders grind against the rotors and drums causing damage to them. 


Air Conditioning & Heating Services

Our air conditioning and heating inspection thoroughly examine intricate A/C system components and their performance. This check is well worth it and helps prevent you from taking a beating from the heat.

  • Importance of maintaining your A/C: Heating and A/C systems may eventually break with usage over time, and hose pipes may clog and drip if not serviced, causing reduced efficiency heating and cooling capabilities. 

  • Indications your A/C system may be having issues: Your air conditioning blows only slightly cooler air compared to the exterior air; air blowing in smells damp, musty, or like mildew and mold; air does not warm up in cold weather; the defroster takes longer than normal to operate; heater or A/C only functions when driving, not when idling; heating system blows cold air or the air conditioning blows warm air; and low airflow even at the highest fan setting


Belts & Hoses

A fan belt, also known as a drive belt, is a belt connecting your car's engine to the front-mounted accessories. The fan belt rotates the water pump and engine fan, which maintains a cool environment for the engine and its components. When you are ready for a replacement you can count on ALS Smog & Repair for all your vehicle's repair needs. You not only have to get the belts and hoses replaced with quality ones, but you should have the work done by experts.



Radiators cool your car's internal combustion engine by circulating an engine coolant through the engine – it then loses the heat to the atmosphere through radiation. When the radiator fails, the excess heat produced by the engine could damage the engine components. To prevent this from happening, have your radiator serviced regularly. 


Oil, Lube, and Filter Change

Engine oil is what lubricates a car’s engine, allowing it to run smoothly and last longer. Car owners must maintain a car’s engine by changing the oil and using the oil appropriate for their car's make and model. Experts recommend changing the oil and oil filter in your vehicle every 3 months or 3,000 miles, whichever is first. Oil changes at 7,500 miles are usually too long an interval for most common driving conditions. Each vehicle's manufacturer has its own recommended oil change frequency, so check the owner’s manual and follow the manufacturer’s recommendations. If you're still not sure how often you need an oil change, bring your vehicle into ALS Smog & Repair, and we will be happy to help. 


Tire Balance and Rotation & Wheel Alignment

Improve your vehicle’s handling, increase tire life, and drive with safety by checking your tires every month to ensure that they are inflated with the right amount of air pressure. Wheel balancing has the potential to relieve some symptoms of improper tire wear, like excessive lean. However, improper tire wear may also be the cause of alignment issues. During any tire repair service, our staff will be able to determine whether a tire balancing or rotation service can solve your current set of issues.
