Brake grinding is one of the most common sounds you’ll hear when driving and it can be caused by a variety of factors. The concern is how to fix grinding after new pad and rotor.. Most commonly, it’s due to worn out brake pads or rotors. However, there are a few other things that can cause this noise:
Check your pads
If your pads are worn, you’ll need to replace them. If they’re not, continue.
For checking the pads for damage:
- Bend a pad in half and look for cracks or holes. If there is any visible damage, you will need to replace them.
- Use a small piece of sandpaper to test the surface of each pad where it touches the rotor. The surface should be smooth and free from any gouges or rough patches that could cause excessive wear on either component moving against each other later down the road if left unaddressed now; if so, replace your pads as needed before continuing with further diagnosis below since this may also be indicative that other parts/components such as rotors/brake kits are also worn beyond their normal life expectancy too which would require replacing those components too before long anyway so might as well do so now instead trying save some money by skipping over replacement but having issues later due to neglecting maintenance now rather than waiting until it happens again later down road when maybe even more expensive repairs might occur due lack funds available at time due not taking care preventive measures earlier which could’ve helped avoid whole ordeal altogether now costing much more than just doing preventative upkeep right away instead waiting until problem happens again when already having spent money on last set fixed issue(s) caused by neglecting earlier fixes.”
Check the pins and pistons
- Check the pins.
- Check the pistons.
Check that all guide and lining pins are smoothly fit into their respective holes, without any signs of wear or damage to either the guide pins or their associated pistons. Look for cracks in these parts as well, and make sure that none of them have been damaged during installation or removal from your car. If you find any problems with these components, replace them before continuing with this guide’s instructions for pad replacement/installation.
Inspect the caliper guide pins
Inspect the caliper guide pins for damage, wear, corrosion, bends, cracks and rust. It’s also important to check that the pistons are aligned properly with the pads and rotors so as not to damage them.
Check for warped rotors
- A warped rotor is a rotor that has been damaged by heat, which causes the center of the rotor to be higher than the edge.
- First you need to check for this by using a straight edge across the face of the rotor. If there is any distance between either side of your straight edge and your brake pad then it could be warped rotors and will need replaced.
- To fix this problem you can try heating up your brakes with a propane torch so they expand back into shape or taking them off your vehicle and hitting them with hammer until they are flat again but most likely if you have these issues it will require new rotors being installed on either side of your vehicle
Do a thorough brake job
- If you haven’t done a brake job recently, now is the time to do one. A thorough brake job involves:
- Flushing the brake lines
- Replacing pads and rotors
- Replacing wheel bearing(s)
- Check your car’s alignment, too. If your wheels are out of alignment, it can cause excess wear on your brakes and lead to grinding noises in some cases. Getting an alignment should be done once a year or every other oil change (or every 6 months if you drive mostly city miles).
Grinding noise can be caused by many factors including worn out pads and caliper guide pins.
Grinding noise can be caused by many factors including worn out pads and caliper guide pins. Here are some things to check:
- Inspect the caliper guide pins and pistons. If they’re worn, you may have to replace your brake pads or rotors.
- Make sure your rotors are not warped. Warped rotors will cause the car to pull when braking, which results in grinding sounds when applying your brakes. To fix this issue, do a thorough brake job on your car and replace any parts that need replacing (i.e., warped/worn out brake pads).
New rotors, new pads, grinding when I stop.
If you’ve replaced your pads and rotors, but the grinding continues after stopping, then you need to check the following things:
- Make sure that the new pads are a suitable fit for your car. If they are, check again and make sure they’re all properly installed with no movement in any direction.
- Check that there is no play in the caliper slides or bolts (caliper mounting bracket). This will cause uneven pad wear. Also check that there’s no binding caused by spongy brake fluid in the front master cylinder or rear lines; this can reduce braking efficiency and cause excessive heat build-up on the rotors during hard braking situations. A faulty master cylinder will also often leak when pushed under pressure which can affect both braking performance as well as steering feel due to fluid splash onto tie rod ends or other suspension components at high speeds
Sounds like the nipples that hold the caliper to pads didn’t get pushed back into the caliper.

If you have new pads and rotors, you need to remove the calipers and put them on a bench vice. You will then need to push the pistons back in a little bit and try it again. This is only for cars with rear disc brakes. Read more: Car Suspension Problems
When they pushed your pads in and slid the rotor back on they should have pushed your pistons back, if they didn’t you got a bad mechanic.

You can do this yourself, it’s easy. You need a vice, some plywood blocks and a hammer to hold the caliper with. Take off all 4 wheels so you can see what’s going on inside the calipers!
Get out your rubber mallet (not metal!) and gently tap the piston back into place until it is flush with the outside of your caliper. Then re-install everything as per normal: rotors/pads/caliper. Read Also : Top Secret to Save Your Car Driveshaft
This is a sticky subject so this is not all there is to know
This is a sticky subject so this is not all there is to know. This article will only address the first step in solving the grinding problem, and it’s an easy one!
The next steps are to replace your rotors and calipers or pads if they are bad. The last thing you want to do is put new pads on an old rotor and then have them grind again after spending $300 on pads.
Conclusion
The most important thing you can do to fix grinding after new pads and rotors is to make sure you are using high quality parts.
