Why Replace Your Own Brake Pads?
Over time, or with heavy use, a vehicle’s brake pads wear down and need replacing. Fortunately, with some basic car knowledge, you can replace them yourself and potentially save hundreds of dollars. Even if you don’t plan to do the job yourself, understanding the process can help you better communicate with your mechanic when the time comes.
Car Lift For Sale Brake pads are a crucial component of a vehicle’s braking system, which allows the car to slow down and stop. Worn brake pads often produce squealing or grinding noises. Since most modern cars have front disc brake systems, the front brake pads typically wear out faster than the rear ones and thus need more frequent replacement. It’s essential to change the pads when they become too thin, especially if you hear persistent squealing or grinding when applying the brakes. However, noise alone isn’t always the best indicator, so it’s wise to periodically check the pad thickness.
Note: If the front end of your car vibrates when you apply the brakes, it may indicate warped brake rotors. Grooved or uneven rotors may also need to be replaced or resurfaced, which is a more advanced repair best handled by a professional.
This Car Lift For Sale brake pad replacement guide was performed on a 2009 Ford Flex, but the basic principles apply to most vehicles. Here’s a step-by-step guide to replacing brake pads:
Tools You’ll Need:
– Disposable mechanic’s gloves
– Jack and jack stands
– Lug wrench
– C-clamp or wood to retract the piston
– Wrench (socket, open-end, or adjustable)
– Turkey baster for drawing out brake fluid
– Plastic tie, bungee cord, or string
Materials Required:
– New brake pads (consider buying original Car Lift For Sale manufacturer pads for better quality)
– Brake fluid (refer to your owner’s manual for the correct type)
Important Notes Before You Begin:
– Caliper Assembly: Most cars have a sliding-caliper brake assembly, as shown in the guide. Some have fixed-caliper assemblies, which are also easy to change but require a slightly different process.
– Do One Side at a Time: Finish changing the pads on one side before moving to the other. Turn the steering wheel to angle the wheel you’re working on outward for easier access.
How to Change Brake Pads, Step by Step:
1. Remove the Wheel: Loosen the lug nuts, jack up the car, secure it on a jack stand, then fully remove the lug nuts and the wheel.
2. Remove the Slider Bolt: Locate and remove the lower slider bolt that holds the caliper in place.
3. Pivot the Caliper Up: Pivot the caliper upward without disconnecting any hydraulic brake lines.
4. Slide Out the Old Brake Pads: Remove the old brake pads, which should slide out easily.
5. Replace the Retaining Clips: Install the new retaining clips that come with your brake pads.
6. Slide in the New Brake Pads: Install the new pads, ensuring they fit snugly into place.
7. Retract the Pistons: Use a C-clamp or wood to push the pistons back into the caliper to accommodate the thicker new pads.
8. Monitor the Brake Fluid Level: Keep an eye on the brake fluid level as you retract the pistons to avoid overflow.
9. Reposition the Caliper: Lower the caliper over the new brake pads.
10. Reinstall the Slider Bolt: Secure the caliper by reinstalling and tightening the slider bolt.
11. Repeat for the Other Side: Follow the same steps on the other side of the car.
12. Test-Drive Under Safe Conditions: Test the brakes in a safe environment to ensure everything works properly.
FAQs
How often do you need to change your brake pads?
Consult your Car Lift For Sale owner’s manual for specifics, but typically, you should replace brake pads when the vehicle signals a need, either through sensor alerts or noticeable noises like squealing or screeching.
How much does it cost to replace your brake pads?
The cost varies depending on your vehicle type, the braking system, and whether you choose original, aftermarket, or performance pads. Generally, you can expect to pay between $115-$300 per axle, with higher costs for luxury or performance vehicles.
Understanding Your Braking System for Easier Brake Pad Installation
Knowing how your Car Lift For Sale braking system operates can make replacing brake pads simpler. In a disc brake system, the brakes consist of round discs called rotors and brake pads. The pads are positioned on either side of the rotors, and a brake caliper grips both the rotor and pad, connecting the brake to the rest of the system.
The brakes are located behind the wheel, and the rotors spin along with the wheels. When you press the brake pedal, a brake booster behind it changes the pressure in the master cylinder, causing brake fluid to flow through the brake line.
At the other end of the brake line is a piston. The fluid pushes the piston, moving the pads against the rotor. This creates friction, which slows down the rotors, and as they decelerate, the wheels also slow and eventually stop.
Car Lift For Sale Brake pads and rotors are usually replaced simultaneously, though this guide focuses only on brake pads. The instructions apply to ceramic and semi-metallic brake pads, which are commonly used in most vehicles. Check your owner’s manual for additional details on changing brake pads.
When brake pads begin to wear out, you might hear squealing, squeaking, or grinding noises. If your car pulls to one side more than the other when you brake, or if you feel a bouncing sensation when pressing the pedal, it may be time to replace the brake pads.
Preparing Your Car Lift For Sale Vehicle
Before replacing the brake pads, prepare your vehicle. Start by loosening the lug nuts on the tire with a tire iron, but don’t remove them completely. Slide a floor jack under your car in the spot specified in your owner’s manual, then pump the handle to raise the vehicle. Once raised, place a jack stand underneath to support the vehicle’s weight and remove the jack.
Safety Tip: Floor jacks alone don’t provide enough support, so always use jack stands for added stability. Working under a car supported only by a jack can be dangerous.
