Brake pads comprise of grating material that is clung to a strong steel support plate. When you push on the brake pedal, the rubbing material on the brake pads is constrained against the inward and external surfaces of the steel brake rotor under colossal weight. The subsequent contact makes the wheels on your vehicle slow quickly taking into account a brisk and controlled stop. After a large number of miles, this grating material erodes, and the brake rotor erodes also, requiring substitution.

What are brake pads?
What's included in a brake pad replacement?
Procedures will vary depending on engine design but generally the procedure is as follows:
- Affirm the thickness of the rest of the material on the brake pads. On the off chance that the rest of the contact material is under 2 mm in thickness, pad substitution is justified.
- Outwardly assess the brake disk surface that contacts the pad (for scoring, setting, furrows, rust) and measure the brake disk with accuracy instruments for thickness variety, run-out and possible warps.
- Investigate the caliper, torque plate, cushions, and disks to decide whether the caliper is working uninhibitedly.
- Put in new cushions and any extra prescribed parts (e.g., disks, if disks withdraw from OEM particulars).
- Grease up slowing mechanism segments, for example, caliper sliding pins, and investigate the state of the brake fluid. Top off brake fluid as required.
- Lastly, the technician will test drive your vehicle to affirm ordinary activity of the braking mechanism.
How to diagnose a brake pad issue
Wear indicator on vehicle dashboard.
At the point when the grating material on the brake cushions is worn to inside 2 mm of the cushion support plate, substitution of the cushions is vital. Most fresher vehicles today have hardware incorporated with the brake cushion. At the point when the cushion is at a point that it should be supplanted, an image will show up on your vehicle dashboard’s instrument group.
Sharp screech while braking.
At the point when the rubbing material on the pads is worn near the support plate, you may hear a screeching or squeaking clamor as you drive paying little mind to whether you are applying the brakes or not. That screeching or squeaking clamor is intended to make you mindful that the brake cushions are getting low and should be examined. On the off chance that the majority of the grating material on the brake pad has been heavily eroded, you will hear granulating and scratching noises when you apply the brakes. Pad substitution is required now and the vehicle is perilous to drive until amended.
Brake pedal throb or vehicle vibration.
After some time, brake disks may create inordinate thickness variety (>.001 inches), intemperate runout on the wheel center point (> .002 inches), or the brake disk may twist because of high working temperatures. In the event that these deformities exist, you may see throb in the brake pedal or steering wheel during braking. New pads and disks will be required if the disk has any of the previously mentioned inefficiencies.
Vehicle pulling or meandering on braking.
If your your vehicle drags to one side during braking, that could be an indication of a seized brake caliper, misalignment of the suspension, and now and again tire deformities or uneven tire expansion from side-to-side. The technician who examines your vehicle will decide whether new brake pads alone will settle the issue or if further fixes are required.
High mileage on existing pads.
Despite whether any of the above stopping mechanism side effects happen, each 15000 miles a technician should evaluate the thickness of the rest of the pad material on the brake pad and play out an intensive visual examination of the braking mechanism.
Braking mechanism cautioning lights.
Should your braking mechanism cautioning light illuminate, or a stopping mechanism related support update message shows up in the drivers data, have your vehicle investigated and fixed at the earliest opportunity.
