A Quick Guide to Brake Disc Replacement

Driving with a faulty brake disc is probably one of the most dangerous problems that you can have in your vehicle. It's like walking on thin ice and your car becomes an accident waiting to happen. If you think your ride is currently showing signs of faulty brakes, you'd better look into it before it's too late.

Replacement Symptoms

After some time, your vehicle's front discs will become too thin and need replacement. After all, bearing 80% of your vehicle's stopping power is no walk in the park. Rear discs, on the other hand, will most likely wear out due to corrosion. Here are some telltale signs of faulty brakes:

  • Rumbling - Hearing a loud metallic sound is an indication that your brake disc is already in contact with the brake caliper due to worn out pads.
  • Fading - If your brakes have reduced responsiveness and the pedal feels deep or sinking towards the floor, chances are there's a leak in your braking system. You can also check by looking if there's a puddle of fluid when parking your car.
  • Pulling - When stopping literally becomes a drag?your car is pulled to one side when braking?you might have uneven brake linings or your brake fluid might be contaminated.
  • Vibrating - A vibrating brake pedal may indicate either a warped rotor or a misalignment in your vehicle.

Replacement Cost

Your total cost will depend on the damage of your braking components and the brand of replacement parts that you will choose. Note that you'll often need to change your brake pads or calipers every time you replace your discs. In general, brake disc and pad kits can range from $100 to $400 while brake disc and caliper kits cost around $250 to $500.

Replacement Process

With some patience and the right tools, repairing your brakes can actually be easy. Here's a quick and basic guide to replacing a brake disc.

Difficulty Level: Easy

Tools that you'll need:

  • Jack and jack stands
  • Lug wrench
  • Phillips head screwdriver
  • Dead blow hammer
  • Ratchet wrench set
  • C-clamp

Step 1: Begin by finding a flat surface where you can park and work on your car. Next, secure your vehicle using the jack and jack stands.

Step 2: Remove the brake caliper by unbolting it and hanging it out so that you don't have to remove the brake line.

Step 3: Next, carefully remove the carrier holding the caliper and the pad by unbolting it, making sure that you protect and set aside the bolts.

Step 4: At this point, you can start removing the old brake disc by using the Phillips head screwdriver to unbolt the screws holding it in place. If the screws don't come out, you may need to drill them out. When the screws are removed, slowly take the old disc out from the hub.

Step 5: Finish by sliding the new brake disc onto the hub and bolting it to secure it in place. Then, reattach the carrier and the brake caliper by bolting them in.
