Oh, Stop! (Disc Brake Service)

Every time you drive your vehicle, you wear down your brakes just a little bit.  And after a while, that adds up.  Gradually, your stopping power isn't like it used to be.  Since brakes are one of your vehicle's most important safety features, it just makes sense to keep them performing well.

Most vehicles have disc brakes.  One key component, as the name suggests, is the disc.  Most vehicles have discs on their front and rear wheels.  The discs (also called rotors) are made of metal, and each rotates with the wheel hub.  Your brakes also have pads that make contact with the rotors when you press down on the brake pedal, and the friction stops your vehicle.

After many, many stops, that friction wears down both the pads and the discs and reduces their ability to stop the way you need them to.  The discs may also become uneven from all the heat they generate, and your brakes won't stop as well as they used to when they were newer. 

Some signs that your rotors need attention include vibration at the wheels when you stop, discolored rotors (the metal looks blue), excessively hot rotors, or grooves in the metal.  If you see any of these signs, it's time to bring in your vehicle for us to inspect your brakes. 

A technician will measure the thickness and trueness of the rotors and check the surfaces for wear.  If they need to be replaced, they'll be done in pairs, so if a front rotor is bad, the other front rotor will also be replaced. Usually, your brake pads will be replaced at the same time.  You can ask your service advisor if higher-performance brakes would benefit you.

When your vehicle is at the shop, the technician will check other components of your brake system to make sure they are operating safely. Brakes are vital to the safe operation of your vehicle.  Keep them well maintained so they can be there when you need them.

A Real "Pane" (Window Maintenance and Repair)

It's pretty frustrating when your driver's window won't work.  You can't get your food at the drive-thru without opening the door, have a tough time using the ATM from your vehicle, can't have that fresh breeze blowing through your hair as you listen to your favorite road tunes.

Plus, there's a safety factor.  Your windows provide an escape route in case you need to get out and the doors won't work.  Let's take a look at what's going on when your window won't operate.

Most vehicles these days have power windows.  They have an electric motor in each power window and sometimes those fail.  They often give you a warning that they're on their last legs by making a noise or hesitating, so if you get a sign like that, have a technician check it out. Loss of power can also be due to a blown fuse, a bad switch or faulty wiring.

All windows have something called a regulator that moves the glass up and down.  They have a lot of moving parts in them which can break, become bent, rust or get out of alignment. The glass moves along a window track guide.  Sometimes if the glass gets out of the track, it won't move up and down the way it's designed to do.

When you take your vehicle over to a repair facility, a technician can pinpoint the cause of your malfunctioning window.  Often it involves having to remove the door panel to gain access to the components inside.  But when everything's working right, you'll be able to throw that annoying inconvenience right out the window.

Don't Blow a Gasket! (Valve Cover Gasket Replacement)

When you head out to your vehicle after it's been parked and notice oil leaking underneath it, that's something to have looked at right away.  Oil leaks mean your oil level is probably low and running a vehicle in that condition can lead to expensive repairs.

While there are many reasons oil leaks develop, one possibility is a bad valve cover gasket.  Vehicle engines have a cover bolted over the spot where the engine valves are, and that cover keeps the oil inside the engine. In between the cover and the engine is a gasket that keeps that seal tight.  But after many years of high engine temperatures and vibrations, that gasket or the bolts that hold on the valve cover can fail or loosen, and oil can leak.

You may see dirty oil on the valve cover in the engine compartment, near the spark plugs, or around the bolts that hold the valve cover on.  All those are signs of leakage and time to bring your vehicle in for our technicians to check out.

In some vehicles, taking off the valve cover and replacing the gasket is a relatively easy job. In some models, though, other engine parts are located near that part of the engine and must be removed to get at the gasket, so repair costs can vary widely.

The technician will measure to make sure the valve cover isn't warped so it can be reused. If it is warped, they'll recommend replacing it with the gasket.  

While the technician has that area of your engine accessible, they will also check to see if other components need replacing at the same time, which could save you money.  And because valve cover gaskets usually fail in older vehicles, the technician will check for other oil leaks then, too. 

One of the best ways to be sure your valve cover is doing its job is to have your vehicle regularly maintained.  The technician will periodically look over your engine compartment and make sure you know when things are showing signs of age and wear BEFORE they fail and leave you stranded.

Give me a Brake (Light)!

If that little brake warning light pops up on your dash, do you know what it means? Well, if you said no, you wouldn't be alone. You know it has something to do with your brakes, but exactly what? You're not sure. One of the reasons is that it could mean a lot of different things.

It could be something simple, like you put your parking brake on and forgot to take it off. Easy fix, you're on the road in seconds.

Or, it could mean there's something wrong with your anti-lock brake system. That is a pretty complex symphony of speed sensors, computers and wiring, and sometimes things get a little out of whack. You could have a defective sensor or some wiring may have gotten damaged or come loose. A trained technician at Garrigan's Auto Repair Shop with special equipment can sort it all out.

It's also possible you have low brake fluid. That could be caused by a number of things. One simple reason is that your brake pads have worn down. Replacing them could solve the problem. Another possibility is that you have a leak in your brake system. That could be serious. If your brake fluid level gets really low, your stopping power goes down along with it, and a vehicle that can't stop is a safety hazard to you and others on the road.

Of all the warning lights on your instrument panel, pay attention to the brake warning light. If it comes on, come on over to Garrigan's Auto Repair Shop very, very soon. A vehicle is great when it's moving. But if it can't stop, well, that is a disaster waiting to happen.

We’d love to hear from you. Let us know if you have any questions.
