Racing legend Richard Petty once said, "If you've got good brakes you can stay out of a lot of trouble."

One might say the most challenging part of being your friendly and knowledgeable Keller's Pro Auto & Diesel in Parker is diagnosing a problem before it can be fixed. Cars are made up of a bunch of complex systems.

A recent report stated that over 80% of the vehicles on the road have one or more service item or repair that's needed but hasn't been taken care of. Now that's a lot of undone service. That translates into something over 160 million vehicles in the US alone. Some of the neglected items are minor. Others are serious safety concerns.

Basically, the power brake system helps you provide braking power so that you don't have to do all the work with your brake pedal. The brakes themselves are applied at the wheel using hydraulic pressure.

Your radiator hoses carry coolant between your engine and radiator. It’s an important job. If a hose fails, you could lose your engine coolant which might lead to overheating and very expensive engine damage. So you want to make sure you always have good hoses.

The thermostat is part of your cooling system. Parker residents' vehicle thermostats perform a similar function to the thermostats in their homes. At home, you set your thermostat to maintain a comfortable temperature range. When your home gets too hot, the air conditioning kicks on and when it gets too cool, the heater turns on.
