Are you conversant with how to fix a brake rotor? Brake rotors, depending on their particular condition, should be refinished or changed when the brakes are realigned. They absorb much of the heat produced by the friction of the brake pads against them during braking. Things like stress cracks, deeply pitted places from rust, getting out of round (run out), deep grooves in the surface, or being worn down to minimum specifications or the discard thickness are signs that it is time to change the brake rotors. Before changing the rotors, you can repair them by filing them down (to lower the uneven spots) or taking them to a mechanic to ‘true-up’ or re-shape appropriately. Here is what you will require to do to repair the brake rotors, in an attempt to save some money on the change.
Step 1 – Inspect Manufacturer Specifications
Draw out your automotive manuals and read through all of the manufacturer’s specifications and recommendations. After reading through the information and you are not comfortable with what is needed for the repair, then you are best to take your vehicle to a certified repair technician.
Step 2 – Test Drive Your Vehicle
Before you start to repair your brake rotor, take your vehicle for a light drive on a highway or freeway. Once you are at a good speed, and ensuring there are no other cars around you, mount a light, constant pressure to your brakes. You need to see whether or not you are getting any vibration when you apply the brakes. If you are feeling strong vibrations, you will have to see a professional to re-machine the rotors. If there are very mild vibrations, then you can actually file down your rotors to repair them yourself by following the directions given below.
Step 2 – Jack Vehicle Up
Start by lifting the vehicle up in the air. Using a set of car ramps or a jack, put the vehicle up so that you can easily walk around the vehicle and get to the wheels.
Step 3 – Remove the Wheel
Pull off the lug nuts and remove the wheel of the vehicle
Step 4 – Pull off the Brake Pads
Remove the brake pads very carefully to expose the rotor.
Step 5 – Pull off the Rotor
With the right amount of torque, remove the lug nuts that hold the rotor in position. You will need the right socket to take the rotors off correctly
Step 6 – Then file the Rotor
Using a small file, meant to file down a brake rotor, gently file the surface until you get an even and smooth surface. Do not attempt to over file.
Step 7 – Re-Assemble
Then begin reassembling your braking system for that wheel. Put the rotor back on and tighten into position. Add a little lubricant. Put your brake pads back on second and then put the wheel back on. Ensure everything is tight. Proceed to each wheel, as needed.
Step 8 – Test Drive
Take your vehicle out for a test drive on local roads first. Then go onto highway or freeways.
