Brake Pads on Mercedes GL450
Make sure the brake pads on your Mercedes GL450 have been replaced at least once per year, or as required by your specific make and model of car.
You can tell if they need to be replaced because they will start making a loud noise when you apply the brakes – this is normal wear and tear on the pad and should not be ignored.
If you are unsure whether or not your brake pads need to be replaced, take them to an auto mechanic for inspection; it’s better to do this sooner rather than later so that any necessary repairs can be made before something worse happens.
Always use caution while driving with worn-out brake pads; if there is an emergency stop needed, don’t hesitate to pull over onto the side of the road until you can get help – even if it means delaying your trip home by a few hours.
Tools You Need to Change Brake Pads on Mercedes GL450
If you’re looking to change your brake pads on a Mercedes GL450, you’ll need the following tools:
-Brake pad tool
-Pliers
-Screwdriver
-Cable ties or chain
Brake Pad Tool
This is the tool that you will need to change your brake pads on a Mercedes GL450.
It has an adjustable screwdriver blade which makes it easy to remove and replace the brake pads without having to remove any of the other components of your car’s braking system.
Caliper Hammer
This is another tool that you will need in order for you to change your brake pads on a Mercedes GL450.
This hammer allows you to break off the old pad and install the new one with ease, without having to damage any of the surrounding parts of your car’s braking system.
Socket Wrench Set
You’ll also need a socket wrench set when changing your brakes on a Mercedes GL 450 – this set includes both standard and deep sockets, making it easier for you to access all of the bolts needed in order for you to swap out your brakes.
Torx Screwdrivers
A Torx driver is essential in order for you to loosen or tighten screws – especially those found inside cars’ mechanisms – like those used in brake systems.
Emergency Breakaway Clamp Kit
In case something goes wrong while working on replacing or servicing important automotive equipment like brakes, always have an emergency breakaway clamp kit nearby just in case things go south quickly.
This kit comes equipped with everything needed including clamps, wire cutters, and sandpaper so that if all else fails, at least you won’t lose anything important during disassembly.
How To Change Brake Pads on Mercedes GL450
If your brake pads are worn down, it’s time to change them. Follow our step-by-step guide to changing the brake pads on a Mercedes GL450.
Disconnect the negative battery cable
To remove your brake pads, you first need to disconnect the negative battery cable. This will allow you to safely work on the car without fearing for its electrical system.
Remove wheel
After disconnecting the battery, it’s time to remove the wheel and tire. You can do this by using a wrench or socket set to loosen the bolts holding them in place.
Loosen brake booster hose
Next, we need to loosen the brake booster hose from its connector on top of the reservoir (see photo below). Do this by turning it counter-clockwise with a hex key or Allen wrench.
Remove front rotors
Now that we have removed both tires and wheel, it’s time to take out our rotor(s). To do so, use an impact tool – like an Impact Wrench – and hit each one at least 2 times until they come free from their hubcaps (or other suitable location).
Please note: If your Mercedes has ceramic composite rotors instead of regular steel rotors, then you will also need to remove their coating before proceeding further.
Position new pads on studs
Now that our rotor is gone and all four brakes are free from obstructions – including any old pads – it’s time to position our new ones onto their respective studs according as shown in the diagram above.
Make sure there is enough space between each pad and rotor so that heat doesn’t build up during braking which could damage either component.
Insert pistons into cylinders
Finally, once everything looks good down where it counts (), screw in your piston caps until they’re secure.
When to Change Brake Pads on Mercedes GL450
If you’re noticing a decrease in braking performance, it’s time to replace the brake pads on your Mercedes GL450. Brake pads are worn items and should be replaced every 7-10 years or when they show signs of wear.
When Brakes Feel Less Than Effective
If your brakes feel less than effective, it may be time to replace the pads and rotors. This is because brake pads wear down over time and stop working as effectively as they once did.
The symptoms of this issue are usually a feeling that you need to apply more pressure when braking, reduced stopping power, and unevenness in the pedal feel.
Makes A Noise When Stopped
If your vehicle makes a noise when stopped, it may be time to have the brake pads replaced.
This type of noise can often be caused by worn or warped brake pad material rubbing against each other while you’re parking or driving.
It’s also possible for a disc rotor to become contaminated with rust or debris which will cause noises when you try to stop your car.
Brake Pads Are Fading or Burnt Out
If you notice that your brake pads are fading or burnt out, it may be time to replace them before they completely fail.
Brake pad material wears down over time and eventually becomes ineffective at stopping cars from quickly moving forward again – this is especially problematic on wet roads where hydroplaning can happen easily.
Sign Of Discoloration on Your Brakes
Discolored brakes are typically an indication that there is something wrong with your braking systems – such as corrosion on the discs or braided lines connecting them together.
FAQs
Can I Replace Brake Pads Myself?
You can replace your own brake pads if you have the tools and know-how.
Can I Just Replace Brake Pads and Not Rotors?
Brake pads and rotors should be replaced as a set.
What Happens if You Don’t Replace Brake Pads?
If you don’t replace your brake pads, the brake pads will wear down and the brake system will become less effective. Eventually, the brake system may not be able to stop the car.
Do I Need New Brakes or Brake Pads?
Brake pads and brakes may need to be replaced if they are heavily worn less than 1/4 inch or if the brake system does not function properly.
