Good brakes are obviously very important. If you've ever had your brakes go out while you're driving around the Los Altos area, you'll know how terrifying it can be. Today we'll focus on how to tell when you have a brake problem and how to make good repair choices.
Often, the first indication that something's wrong with the brakes is an unusual sound. It could be a squeal, chatter or grinding sound.
Some brake pads have a little piece of metal embedded in them that will make a squeal or chirping sound when the brake pads have been worn down to the point that they need to be replaced. It's an early warning indicator.
When you hear that sound, schedule an appointment at Allied Auto Works soon.
Now a chattering sound is more urgent. That usually indicates that something is loose. It could be a brake pad or even the brake calipers. If one of those parts falls off, you could have some serious trouble stopping the vehicle. It would be a good idea to park it until you can get into the shop.
A grinding noise usually means that the brake pad is completely worn away and the metal parts of the brake are rubbing directly on the metal brake rotor. That means the rotor is being damaged and will need some work. More on that later.
Another warning sign is that your brake pedal may feel soft and spongy – or it may even feel very hard to push in. Both could mean trouble. And of course, you may get a dashboard brake warning light.
Now when it comes time to replace your brake pads, you have a choice to make. You can get the same pads that came standard on your vehicle. You can expect the same performance and durability as with the pads that came on the car from the factory.
Now you can also get a budget brake pad. Sometimes Los Altos drivers insist on lower cost pads. That's OK if the budget demands it, but you need to be aware of the tradeoffs. Lower grade pads are usually noisier, so you'll have to live with more noise when you apply the brakes. They also tend to generate a lot more brake dust, you know, that black dust that accumulates on your wheels. And they probably won't last as long either. In our opinion, that's a lot of compromise for just a few dollars in savings.
You can also choose to buy premium brakes pads at Allied Auto Works. These perform at higher specifications than the factory pads. You can expect quieter operation, less brake dust and better stopping power.
Now, getting back to the rotors. The rotors are the discs that the brake pads clamp down on to stop the vehicle. If you've been driving with completely worn brake pads, you've scratched grooves into the rotors. If the grooves aren't too deep, the rotor can be resurfaced. A thin layer of metal is cut off the surface of the rotor to make it smooth again.
Now, if the grooves are too deep or if the rotor has already be resurfaced before, there may not be enough material to resurface and still have a rotor that's thick enough to safely stop the vehicle. In that case, the rotor will have to be replaced.
Something that's often overlooked is the brake fluid. Your manufacturer has a recommended schedule for evacuating the old brake fluid, cleaning the system and refilling it with fresh brake fluid. This is really important to brake performance.
So here's the bottom line: if you suspect, inspect. If you notice any of these warning signs, have your brakes inspected at Allied Auto Works in Los Altos. Your service advisor can help you make the repair decision that's right for you.
