Introduction to the topic
Cars employ frictional resistance to slow and stop thanks to brakes. In both drum and disc brakes, the brake pads squeeze the rotor or drum inside the wheel to slow the vehicle down. It may seem counterintuitive to use lubrication in a system that relies on friction, yet the right lubricants are essential to the operation of brakes.
Of course, you should never apply lubricants to the brakes’ friction surface. That’s what provides the stopping power, and lubrication would make your brakes useless. But brakes contain many moving parts, and lubricating them all is essential to their proper operation. Lubricants for the brakes not only minimal wear and tear but also prevent the brakes from creating squeaking or screeching noises due to vibrations.
Where should you put brake grease?
Greasing the brake pad, caliper pins, and brake clips is essential for the smooth operation of a disc braking system.
Here, we’ll examine the various components of a brake system and see how grease improves its performance individually and collectively.
1. To replace the brake pad
As a rule, greasing the brake pad is unnecessary and unnecessary grease can cause problems.
However, doing so guarantees that you won’t have to deal with the annoying squealing noise that frequently accompanies the installation of brand-new brake pads. When applying grease to your brake pad, keep in mind these three things:
2. Make sure you don’t go crazy. It only takes a very tiny layer
You should NOT use a lubricant that contains copper. When the rubber on your brakes gets worn down, your stopping power suffers. Instead, you should use a lube made of ceramic or silicone.
Never lubricate the brake pad’s friction side. Avoid using oil on the friction parts of your vehicle’s brakes because it will reduce their effectiveness.
3. Caliper pins
Pins or bolts made of metal are used to secure the brake calipers in place. For their role in “guiding” the brake bad into place, which aids braking, these pins have another name: guide pins. Greasing the caliper pins is crucial for several reasons:
There is no rubbing action along the caliper without the lubricant. The brake pad will wear down more quickly or in patches as a result of this.
On the rotor, they can get caught and spin endlessly. Brake pad wear will accelerate as a result of the increased temperature generated by the brake system.
Brakes lose efficiency without regular maintenance, such as lubricating the caliper pins. It will cost you more money over time to keep replacing the brake pads.
4. Rivets for putting on the brakes
The brake clips are an integral component of the braking mechanism. The clips’ primary function is to provide a level landing area for the brake pads, preventing uneven wear. Although this is true, many modern automobiles also feature clips that move the brake pad away from the rotor, reducing the latter’s wear and tear.
Grease the brake clips so that it moves smoothly as intended rather than dragging or becoming stuck, which defeats the purpose.
What happens if caliper pins aren’t greased?
Most motorcycle brake units are made of aluminum, therefore steel pins will corrode and adhere to the metal.
If the pins are held in place by a pad and the hole is blind, you won’t be able to use a small punch and hammer to knock them out from the back. When the pads wear out, this becomes a serious issue. Copper grease can be used as a preventative measure, but it’s best to just take them out once a year to be safe.
The difficulty with this line of thinking is that most motorcycles have several steel bolts running into aluminum, which leads to the common occurrence of rust. Is it really necessary to take the engine apart every few years? You may wish you had if, after 10 years, you still own the motorcycle and want to take the engine out as part of a thorough cleaning.
When silicone grease wouldn’t be an appropriate lubricant for brake pistons?
When you hear about “brake piston lubrication,” what you’re hearing is the temporary lubrication of the rubber seals that keep braking fluid within the cylinder as the piston glides. While in use, the fluid acts as a lubricant for the seals, keeping them in good condition. We are providing lubricant for the assembly process.
To avoid damaging the rubber and to work well with the brake fluid, the assembly lubricant must meet these two criteria. It’s possible to utilize brake fluid since that’s what lubricates the component throughout its whole useful life. Problems may arise because of the length of time required to assemble the brake component before it can be put into use. When a remanufacturing firm handles the assembly, the completed product may sit on a shelf for a very long time—sometimes years. When the brake fluid is exposed to air, it collects moisture and causes corrosion of the iron elements of the braking component, leaving them useless. The rubber seals of a brake system are particularly vulnerable to damage from petroleum-based materials.
But silicone grease won’t react with anything at all. Because of the thin coating of silicone grease, rubber is protected, braking fluid is not contaminated, and rust is kept at bay. In a nutshell, it functions admirably as a brake piston assembly lubricant. For a long time, I relied on it, and it served me well. To prevent leaks when using a vacuum bleeder on a caliper or secondary clutch cylinder, I pack it around the bleeder nipple base. The silicone oil prevents the bleed nipple from rusting in place, and it also seals the threads for more effective bleeding.

My brakes have started squeaking; what can I do?
A light layer of grease on the backs of the pad and the pieces that clip into place against the wheel will assist eliminate the screaming of the brakes and is not required, but is strongly recommended. Furthermore, avoid getting grease on the brake pad’s contact surface.
It is recommended that grease be applied to the brake pads, but only the caliper pins and brake clips require it. This will keep your brakes in good working order, extend the life of your brake pads, and prevent your brakes from becoming weaker over time.
