    Understanding Smog Requirements in California

    Last updated 2 months ago

    If you live in the State of California, your vehicle must meet strict emissions standards in order to be legal to drive. These smog requirements are designed to help reduce pollution and improve air quality. To be sure that you pass your smog inspection, it is helpful to understand California’s smog requirements before you visit the smog inspection facility. Here is a quick overview of smog requirements in California. 

    History of California Smog Requirements

    California’s smog law was passed in response to growing concern about the air quality of the state. Residents of California were worried that vehicle pollution was affecting their health and quality of life. The smog law was passed in 1963, and continues to be strictly enforced to this day. California’s strict smog requirements have helped to cut down on smog and pollution across the state, especially in heavily populated areas such as Los Angeles.

    Vehicles Requiring a Smog Inspection

    All vehicles in California are required to pass smog inspections, with very few exceptions. Hybrid and electric vehicles are exempt from smog laws, as are certain models of diesel-powered trucks. In addition, vehicles that were manufactured before 1975 are exempted from the law. All other vehicles must undergo biannual smog inspections.

    Passing the Smog Inspection

    In order to pass the smog inspection, a vehicle must be in proper working condition. If you fail your smog test, your mechanic can help you improve your vehicle’s emissions. By repairing your vehicle at a qualified service center, you can help to make sure that your vehicle meets emissions standards and passes the check.

    Exploring the Signs and Symptoms of Failing Brakes

    Last updated 2 months ago

    Most drivers feel safer on the road when they have a sense of control over their vehicles, and nothing screams lack of control like slamming on your brakes and having them barely respond. To avoid this unpleasant and potentially dangerous scenario, keep an eye out and an ear open for these signs that your brakes need service so that you can schedule an auto repair appointment before they fail completely.

    Throbbing Brake Pedal

    If your brake pedal starts pulsating beneath your foot when you apply pressure to it, it may mean that your brake rotors are warped and need to be replaced. After paying a visit to your local auto repair center, make an effort to ease off your brakes when barreling down hills to keep friction from building up and warping your new brake rotors.


    Brake pulling describes the tendency a car has to pull to one side of the road after the brakes are applied. This may be caused by worn down brake linings or contaminated brake fluid, two problems that can be corrected at a full-service auto repair center.

    Grinding Noises

    The grinding, screeching, or squealing of metal on metal is indicative of worn down brake pads. To avoid damaging your brake system, arrange to have your brake pads replaced as soon as you first hear these noises.

    Reduced Responsiveness

    A general lack of effectiveness of the sort that makes you feel like you have less control over your vehicle is indicative of a leak in the brake system. Scheduling a brake repair appointment now will make you feel safer on the road and will probably save you money in the long-term.

    If your brakes display any of these signs, have your brakes serviced as soon as possible. At Walt’s Danville Service, our technicians have the know-how and the equipment to thoroughly inspect and fine-tune your brakes. As a full-service auto repair shop, we can also run a diagnostic and alert you of any other repairs your car may need. To schedule a service appointment, call (925) 394-7839.

    Top Signs That Your Tires Need Rotation

    Last updated 2 months ago

    Road conditions and automotive design causes front and back tires to wear differently from one another. In order to get the most from your tires, it is important to have them rotated a couple of times a year.

    There are a handful of ways to tell if your tires need to be rotated. One of the easiest ways is to check the tread on each of your tires using a penny. If there is much discrepancy between tires and you have not recently had your tires rotated, it is probably time to visit your local auto repair shop. Another way to tell if the time has come to rotate your tires is by keeping an eye on your mileage and making a note to change it in accordance with the manufacturer’s recommended maintenance schedule.

    While tire rotation schedules vary from vehicle to vehicle, most manufacturers recommend rotating your tires after every 3,000 to 7,000 miles. If you are due for a tire rotation and you live near Pleasanton, Alamo, or San Ramon, call Walt’s Danville Service at (925) 394-7839. We can handle all of your auto repair and maintenance needs.
