Car Brake Pad Repair And Replacement
What are car brake pads?
Disc brakes are a standard feature on modern cars. Brake rotors attached to the wheels rotate with the wheel. Brake callipers pressurize the rotors in response to applying brake pressure. The purpose of the brake pads is to metal-on-metal friction. The friction between the rotor and the calliper. It's time to replace the pads. A driver may hear a screeching sound or see the car pull to a stop sign when they apply the brakes. These show signs of wear on the pads. When Should I Change the Brake Pads on My Car? You should change Brake pads after every 25,000 to 65,000 miles. You should change brake rotors after every 30,000 to 70,000 miles on average.
The precise symptoms when changing car brake pads and rotors.
1. Brake-related squeaking or squealing
This is the first sign that your brake pads are getting close to the end of their usable life. When it is a squeaking or screaming sound emanating from the brakes. The most common reason for brake pads to squeal is excessive wear and tear. After you have worn down the pads, you'll hear a grinding sound. After that, your rotors will start to get damaged, increasing the cost of the repair.
2. Grinding Noise When Applying Brake
As mentioned before, you should replace your brake pads as soon as possible. After you hear a grinding sound when you depress the brake pedal. Certain brake pads come with integrated metal wear indicators. They alert you when pads need replacing. You run the risk of suffering far more damage. Pay more for repairs if you let the brake pads grind any further.
3. Shaking While Applying Brake
You apply the brake pedal and feel your automobile trembling. There's a problem with the brakes. The brakes are likely acting since the car's rotors, which aid in stopping it, are no longer smooth. To get your car fixed, you need to take it to a professional.
4. It Took More Time To Stop
It causes a decrease in brake performance. This is a significant indicator that your brakes need maintenance. It could be a sign that your brake fluid is low (usually from a leak). Your brake pads are entirely worn down if you're having trouble stopping while applying the brakes. To make sure you maintain all your braking capabilities. You should see a brake mechanic as soon as possible for a thorough grasp of what's wrong with your brakes.
5. The brake pad indicator illuminates
Brake warning lights are standard on the majority of current cars. It also displays on the dashboard. Your brake system warning light is the other, and the first is your Antilock Braking System (ABS) light. When you use your parking brake, your brake light lights on your dash. It doesn't always come on when there's a problem. If your brake warning light is on and your parking brake is not engaged, have a brake specialist inspect your system.
6. When the Brake Pads on Your Vehicle Are Too Thick
Inspecting your brake pads for wear is a simple way to keep an eye on their condition. Check your brake pad by inspecting the space between the wheel's links.
It's time for new brake pads if it looks to be less than ¼ inch (6.4 mm) thick and there is brake dust accumulation. Do You Have Brake Problems? Allow our knowledgeable brake technicians to diagnose you if you're exhibiting any of the remove signs.
How To Replace Car Brake Pad ?
1. SAFE FIRST
Place the car on a level, dry area and secure the wheels with wheel chocks. Always be sure to safeguard your hands and eyes by using safety goggles and gloves.
When raising the car, use caution. Select suitable jack positions to connect the jack and jack stands.
2. Verify the brake fluid level.
Examine the brake fluid reservoir by opening the hood. It needs to have some fluid evacuated if it's full. This will reduce the likelihood of spillage during the brake calliper piston's compression.
3. HOLD UP THE CAR AND TAKE OFF THE WHEEL
When the wheel is stationary and on the ground, use a breaker bar and socket to loosen the wheel nuts. Using a hydraulic jack, raise the car from a safe location. After positioning a jack stand or stands beneath the proper locations, you can drop the car onto the jack stands. Take off the wheel and the lug nuts
4.TAKE OUT THE CALLIPER AND THE BOLTS
The calliper bolts should be rather easy to access. Turning the wheel to the left or right will help access. After removing the calliper, hang it on a bungee cord. Note: Depending on your car, removing the calliper could need different methods.
5.TAKE OUT THE ROTOR AND OLD PADS
Examine the worn-out pads for any irregularities in wear. Uneven wear might be a sign of a sticky calliper piston, worn pad or calliper hardware, or the pad or pads "sticking." There will be a guide available for checking the brake pad box for uneven wear. After removing the pads, take out the rotor. To remove the rotor on many cars, you'll need to remove the mounting bracket for the calliper. A bolt through the brake calliper attachment bracket secures it to the spindle assembly. Remove the brake calliper and brake calliper bracket before removing the brake rotor. This will make the rotor accessible. Be cautious not to remove the rotor if there is any uneven wear or rust. You need to complete the removal of it from the hub assembly. So, you might need help using a mallet or rust penetrant such as PB B'laster.
6. CLEAN THE SURFACE OF THE ROTOR MOUNTING
To get rid of rust and debris, use a wire brush to clean the hub surface. This will remove the chance of pedal pulsation and guarantee that the new rotor rests flush on the hub. Thin as a sheet of paper, rust might be the source of a pulsating pedal.
7. WASH THE NEW OUTER ROTOR
Get some Brake Cleaner from AutoZone. Skip this step if your Duralast Gold Rotors are rust-resistant.
8. SET UP THE NEW OUTFITTER
Consider you. You're doing great.
9. SETUP BRAKE COMPONENTS
Install new hardware in place of the brake hardware. At low stopping speeds, worn brake hardware produces vibrations. That is audible as brake noise. Every brake service requires replacing these clips. You need to attach the hardware. Make sure to lubricate the slider contact points with brake lubricant.
10. ASSEMBLEMENT OF BRAKE PADS
To ensure proper pad installation, take note of the wear-sensor position orientation. Wear-sensor positioning varies amongst pads. Wear sensors are present on the inner pads of certain pad sets, all four pads of some sets, and not on any of the sets.
11. Fit fresh brake pads.
You look great over here!
12. Examine the piston and brake calliper, then compress.
Examine the brake calliper and piston to check for any leaks of brake fluid. To seat the calliper piston, if the calliper and piston are clean, use the front/rear disc brake pad spreader set. The spreader set is available for free loan from any AutoZone via Loan-A-Tool. Certain rear disc brakes have calliper pistons that screw in. It is necessary to seat the disc brake pad spreader set for them to work.13.Set up the calculator.
Reattach the calliper to the bungee cord after removing it. VERY IMPORTANT: It's important not to overtighten the calliper bolts. This may trigger far more serious issues. To tighten the bolts, start by using a socket and finish with a torque wrench. Via Loan-A-Tool, you may get a free torque wrench at any AutoZone. For exact torque specifications, refer to a service manual.
14. Examine the brake fluid reserve.
If necessary, top off to the most fill line. Ensure the brake fluid reservoir cap is in place before moving on to the next step. This will prevent spills.
15. USE THE BRAKE PUMP
This will verify that the system is operating and that the braking fluid is flowing as it should. Pump the brake pedal while seated in the car until it feels firm. WARNING: Refrain from depressing the brake pedal. This might lead to internal damage to the brake control cylinder mechanism.
16. Examine the brake fluid reservoir once more.
The topping, if required. Immediately remove the cap after filling up to avoid spillage.
17. FIT THE WHEEL AND DEPRESS THE CAR
To find out the right torque for your car, refer to the owner's handbook.
18. CONTINUE ON THE OTHER WHEELS
Before you drive, make sure the brake pedal is firm.
19. SET OUT TO GO SLEEPY?
To break in the new brakes, take a cautious drive. Increase your speed to about 50 mph on a safe road. Depress the brakes and reduce the car's speed to thirty miles per hour. To give the brakes time to cool, keep driving at this speed for two or three minutes. Repeat this process four or five times until the new brakes are ready for regular use. We call this procedure "bedding brakes."
