Brakes are one of the most important safety features on your vehicle that is used on a daily basis. Many cars have two types of braking systems: standard brakes and anti-lock brakes (ABS). The rotor, caliper, and brake pads or shoes make up a standard braking device. If your brake pads wear out and aren’t replaced, your rotors will need to be replaced as well. At Muffler Doctor & Auto Clinic, we want our customers to feel at ease in their cars. That’s why you can trust our professionals with brake repairs and services, but don’t hesitate to ask us questions about why a service is needed or how it happened. Give us a call at (651) 459-7244, and we will be happy to speak with you.

Exhaust System

Your exhaust system contains a muffler, plumbing, and a pollution-reducing catalytic converter. In general, exhaust systems are tough, and problems with them are often a sign that something else in the vehicle isn’t working correctly. Regardless, it’s essential to be conscious of any possible exhaust problems. Muffler Doctor & Auto Clinic’s certified mechanics are experts in the exhaust, custom exhaust and muffler repair service. We work on both sound-absorbing and puzzled chambered mufflers and can fix exhaust issues on all major makes and models. Regardless of the exhaust issue, you’re having; our team is ready to assist you in getting your vehicle back in working order.

Catalytic Converter

A catalytic converter is a device that sits underneath your car and cleans up gases until they are released into the atmosphere. If your catalytic converter fails, you’ll need to get it replaced to get your car back to its low-emissions status and overall performance. Continuing to drive with a defective catalytic converter can result in a loss of power, particularly during initial acceleration, in addition to an increase in harmful emissions. Unfortunately, you cannot save money by replacing your catalytic converter with a used one due to strict emission regulations. Luckily, our auto care specialists can assist you with installing a brand new catalytic converter at a reasonable price.

Why This Service Is So Important


At Muffler Doctor & Auto Clinic, we can inspect and maintain your car on a regular basis for best performance and safety. If you notice any of the following, get your brakes checked right away by a mechanic:

• A high-pitched squeak when applying the brakes
• A scraping or grinding noise when not braking, which may indicate a brake or bearing issue and should be assessed right away
• Shaking or vibration when stopping
• Having to add more pressure to the brakes in order to stop

“All the staff are great. They were honest about my brake repairs and provided options for me. Letting me know that I would be safe driving a few more miles before needing to replace all 4.
Craig said the would inspect a vehicle that I was look it to purchase. Not only did they let me know what items they can repair on the vehicle, they looked up how much it would be to repair the things that showed up with issues.
I would highly recommend them to anyone looking for a trustworthy and capable auto repair shop”
