There is a reason we check your brake fluid when you come in for a service check.  Maintenance pays big dividends and we want to avoid high repair costs for our Jefferson City drivers.  Did you know that brake service isn't just all about the brake pads, drums & rotors?  That we have found low brake fluid to be the cause of a large percentage of brake issues here at Donnie Braun & Sons Auto Repair?  Seriously, brake fluid is an important part of your braking system and with your service intervals being less frequent on the newer vehicles 5,000-10,000 more miles this has become an issue!  Why?...

belt on an engine

Your vehicle's belts and hoses are essential to the cooling, air conditioning and charging systems, and the engine. Don’t take these routine replacement intervals for granted because they can break down and leave you stranded.

What is the purpose and importance of your belts and hoses? The timing belt keeps the crankshaft and camshaft mechanically synchronized to maintain engine timing. Whether serpentine, V-belt, or fan belt (the belts on the outside of the engine), they all transmit power from the front of the engine to accessories that need to be driven, such as the air conditioning, the charging system, and fans. Radiator and heater hoses carry coolant to and from the engine, radiator, and heater core.

Automatic transmissions are, to many, a mysterious aspect of automotive mechanics. Torque converters, on the same hand, are a mystery shrouded within a mystery. Here’s a basic rundown of how torque converters work, and how to know if yours is failing, from Donnie Braun & Sons Auto Repair in Jefferson City, MO.
