Slipping into Fall (Driving with ABS Brakes)

As the weather changes over from hot to colder, drivers will have to deal with more slippery streets.  And it's important to know how to drive with the brakes you have on your vehicle.  In the 1970s, anti-lock braking systems (ABS) started to be installed on vehicles and they've been a game changer for drivers.  Most modern vehicles have ABS and it's important to know how to drive with them. In older vehicles without ABS, the driver applies the brakes by pushing down the pedal.  That, in turn, sends braking pressure to all four wheels at once.  But all four tires don't have the same traction because the road surface they're each on isn't exactly the same. ABS allows sensors to determine when particular wheels are slowing down more quickly.  The ABS then reduces braking pressure to the wheels that are about to lock up.  That way the wheel turns and the tires keep some grip. (You have to have grip to stop.) It's kind of what drivers try to achieve when ... read more

A Sticky Brake Situation (Parking Brake Service and Maintenance)

We've all been there.  You park your vehicle on a steeper than usual hill and worry about it rolling down while you're running your errands.  So you decide you'll use the parking brake.  When you get back, you release the parking brake, hit the ignition, put it in gear and—uh, oh—you can feel the parking brake is still on.  It's stuck.  What do you do now? Welcome to the world of infrequently-used parking brakes.  Yes, they do stick for several reasons. It's common for components to corrode and get locked up.  Sometimes if you have applied it extra hard, it can jam.  Could be a rusty cable, could be a spring that doesn't return the brake to its disengaged position.  Some pieces just break when they're stressed for the first time in a while. A caliper or the pivot arm it's on can also stick. There are a few things you can try to unstick it.  Carefully rock your vehicle by putting it first in drive and then reverse.  You ... read more

Taking the Heat (Batteries in Hot Weather)

Quick question.  Which is tougher on a vehicle's battery, the heat or the cold? Believe it or not, it's the heat.  Think about it.  The battery often sits in the engine compartment next to that motor generating lots of heat.  That can accelerate corrosion in the battery and may even cause water in it to evaporate.  That will weaken the cranking power of your battery and shorten its life span. To take care of your battery, here are a few suggestions.  It's a good idea to have it checked out to see what shape it's in.  At your vehicle service facility, they have diagnostic equipment that can evaluate its condition.  That can help you know how long you can expect it to last before having to replace it.  At the same time, you should have your charging system evaluated.  If your battery is not getting charged properly, it can be in great shape but not very useful when it comes to starting your vehicle.  A technician will also check the ... read more
