There is nothing more annoying than noisy or weak brakes. Your vehicle’s braking system is the lifeline between safety and disaster, especially in a city like Dubai.
If you own a Mercedes-Benz, you would know that even the slightest squeak can disrupt that luxurious ride.
Modern luxury cars are equipped with advanced tech. That means even a simple brake job needs care and precision. And you don’t want to take shortcuts. You never know what can go wrong.
But here’s the good news: if you love to know your machine inside out, there’s a way.
This guide gives a thorough and doable DIY method for replacing your brake pads and rotors.
If you think it’s too much at any point, you can always turn to professionals. They handle Mercedes repair in Dubai with expertise that matches the brand’s class.
If you are ready to learn the DIY way, let’s begin.
Tools and Materials You Will Need
Before you go all the way, gather everything you need. Having the right tools nearby saves you a ton of frustration. Here’s what you will need:
- Lug wrench for loosening the wheel nuts
- Socket set for bolts
- Torque wrench to tighten parts
- Jack and Jack stands for safety
- Brake cleaner to keep things clean
- C-clamp or brake caliper tool to compress the piston
- Gloves and safety glasses for your hands and eyes
And the brake parts? There are OEM and aftermarket options to choose from. OEM parts are great but can be pricey. Aftermarket parts are not always dependable. If you go that route, go for trusted brands.
Pro Tip: Never rely solely on the jack. Always use jack stands. One small mistake can result in major injuries.
Preparation Before You Begin
Preparation is key. Before you get to the job, make sure you:
- Park your car on a flat surface. Engage the parking brake
- Slightly loosen the lug nuts (a half-turn) before lifting
- Use the jack to lift the vehicle. Then place the jack stands under solid points.
- Remove the wheel and set it aside.
Pro Tip: Take a photo of the brake setup before touching anything. This simple act can save your brakes later.
Removing Old Brake Pads and Rotors
Your wheels are off. Now let’s follow the below steps:
Remove the Brake Caliper
Find the two bolts holding the brake caliper to its bracket. They sit behind the caliper and feel a bit greasy.
Use your socket wrench to remove them. Once they are out, gently slide the caliper off the rotor. Don’t let it dangle. Grab a bungee cord or a wire hanger. Hook it somewhere safe and keep the caliper supported.
Remove the Brake Pads
You will now see the brake pads sitting in the bracket. Slide them out. Some may easily come out, and others give you a hard time. Take time to inspect them. Are there signs of uneven wear? Is one pad thinner than the other? If that is so, it could mean underlying issues. It can be a sticking caliper or a misaligned rotor.
Remove the Brake Rotor
Unbolt the caliper bracket to access the rotor fully. Now look for a small retaining screw. It’s usually near the center of the rotor. Unscrew it.
Sometimes, the rotor pops right off. Other times, it feels hard. If it’s stuck, tap around the face (not the edge) with a rubber mallet. A few knocks do the trick.
Inspection
Check the caliper and rotor hub. Also, examine any sensor wires for cracks, corrosion, or damage. Spray the hub area with brake cleaner to remove rust and grime.
A clean surface gives your new rotor a perfect seat. It also saves you from weird noises later.
Installing New Rotors and Pads
It’s now time to install the new parts. Here’s how to do it right:
Installing the New Rotor
Line up the new rotor with the hub. Slide it on and screw in the retaining screw (especially if your model has one).
Add a light layer of anti-seize compound to the hub face before you install the rotor, making sure it doesn’t get on the rotor surface.
Installing the Brake Pads
Retract the caliper piston before fitting the new pads. Use a C-clamp or brake tool for this.
Once that’s done, insert the new brake pads into the caliper bracket. You may need to apply a little pressure. Apply a dab of brake grease to the back of the pads. It helps reduce the noise.
Reattaching the Caliper
Now, slide the caliper over the new pads. Line up the bolts and tighten them to spec using your torque wrench. Don’t overtighten.
Repeating for Other Wheels
Repeat the process for each wheel. Depending on wear, some do the fronts or rears only. Once all pads and rotors are in, put the wheels back on. Tighten the lug nuts using your hands.
Final Steps and Brake Testing
It’s time to lower the vehicle back down. Use a torque wrench to tighten the lug nuts in a star position, ensuring even pressure.
Before driving, pump the brake pedal a few times. It might feel soft at first, but that’s normal.
Take a short test drive at a low speed. Listen to any noises carefully. Feel for smooth stops. Do you find any odd vibrations or noises? Then, double-check your work. Or maybe it’s time to seek expert help.
If you are unsure or spot something off, Mercedes repair in Dubai professionals are just a call away. Having backup makes sense.
Common Mistakes to Avoid
- Not using a torque wrench to tighten bolts
- Forgetting to pump the brakes before driving
- Mixing up the inner and outer brake pads
- Ignoring ABS sensor wires or pad wear indicators
