Changing your brake pads is a manageable task if you have the right tools and follow the steps carefully to help you replace your brake pads: Tips
Always replace brake pads in pairs (both front or both rear) to ensure even braking. Dispose of the old brake pads and any other materials properly, following local regulations. Consult your vehicle’s manual for specific instructions and torque specifications. Welcome to learn more about brake pad types from here：
link hidden, please login to view 1. Tools and Materials Needed
Jack and Jack stands Lug wrench C-clamp or brake caliper tool Wrench or ratchet and socket set Brake pads Brake fluid Bungee cord or string Gloves and safety glasses Wheel chocks 2. Prepare the Vehicle
Park your vehicle on a flat surface and engage the parking brake. Place wheel chocks behind the rear wheels to prevent the car from rolling. 3. Raise the Vehicle
Use a jack to lift the car off the ground, and then place it securely on jack stands. 4. Remove the Wheel
Finish removing the lug nuts and take the wheel off to expose the brake assembly. 5. Remove the Brake Caliper
Locate the bolts on the back of the brake caliper and remove them using a wrench or ratchet. Carefully lift the caliper off the brake rotor. Use a bungee cord or string to hang the caliper from the suspension to avoid putting stress on the brake hose. 6. Remove the Old Brake Pads
Slide the old brake pads out of the caliper bracket. Take note of how they are positioned for proper installation of the new pads. 7. Inspect the Brake Rotor
Check the brake rotor for any signs of damage or excessive wear. If the rotor is in poor condition, it may need to be replaced or resurfaced. 8. Compress the Brake Caliper Piston
Use a C-clamp or brake caliper tool to slowly compress the caliper piston back into the caliper. This will make room for the new brake pads. Open the brake fluid reservoir cap to make this process easier. 9. Install the New Brake Pads
Place the new brake pads into the caliper bracket in the same position as the old ones. 10 Reattach the Brake Caliper
Carefully position the brake caliper over the new brake pads and rotor. Reinsert and tighten the caliper bolts securely. 11. Reinstall the Wheel
Put the wheel back on the hub and hand-tighten the lug nuts. 12. Lower the Vehicle
Carefully remove the jack stands and lower the vehicle back to the ground using the jack. 13. Tighten the Lug Nuts
Use the lug wrench to fully tighten the lug nuts in a star pattern to ensure even pressure. 14. Check the Brake Fluid
Check the brake fluid level in the reservoir and add fluid if necessary. Replace the reservoir cap. 15. Test the Brakes
Before driving, pump the brake pedal a few times to ensure the brakes are properly engaged and check for any leaks or issues. -

The phenomenon that two objects move relative to each other to produce motion resistance between their contact surfaces is called friction, which is called friction. The existence of friction not only increases the power consumption, but also causes the wear of parts' contact surfaces. Therefore, lubricating oil is usually used between the relative moving surfaces of automobile parts to reduce friction. Failure of automotive parts 75% is caused by friction.
Friction can be divided into dry friction, liquid friction, boundary friction and mixed friction according to the lubrication state of the parts.
(1) dry friction
The friction between the frictional surfaces without any lubricating medium is called dry friction.
When the parts are in the state of dry friction, the surface of the parts is abraded sharply, so the surface of the moving parts of the automobile should avoid the occurrence of dry friction as far as possible.
Dry friction and boundary friction are the main friction between the upper part of cylinder wall and piston ring. Dry friction will occur when the journal and bearing are subjected to impact load in the working process.
(2) liquid friction
Two the friction of the friction surface when the lubricant is completely separated is called liquid friction.
In liquid friction, the two friction surfaces are completely separated by a layer of lubricating oil film with a thickness of 1.5-2.0um, which avoids direct contact between the working surfaces of the two parts. Friction only occurs between the lubricating fluid molecules, so the friction resistance is very small, and the wear of the parts is very slight.
Most of the relative motion parts of a car are carried out under the condition of liquid friction (for example, crankshaft and bearing).
(3) boundary friction
Two friction surface separated by a very thin boundary film is called boundary friction.
The oil film thickness is usually below 0.1um. Friction only occurs between the outer molecules of the boundary film, reducing the friction and wear of the parts. But its thickness is very small, and it is easy to be destroyed by impact and high temperature, so it is not as reliable as liquid friction.
For example: between cylinder wall and piston ring; if the work crankshaft and journal between the insufficient supply of lubricant, easy to produce boundary friction.
(4) Mixed friction
The friction between two friction surfaces in the presence of dry friction, liquid friction and boundary friction is called mixed friction.
In the actual working state, the parts usually work under the mixed friction state, and the friction state varies with the working conditions.
