- Lubricate the Back of Brake Pads: Apply a specialized brake lubricant or high-temperature grease to the back of the brake pads (the side that contacts the caliper and piston). Be careful not to get any lubricant on the friction side of the pads or the rotor.
- Check for Wear: Ensure that the brake pads are not excessively worn. If they are, replace them promptly, as worn pads can lead to squeaking.
- Resurface or Replace Rotors: If your brake rotors are scored or have irregularities, consider resurfacing them or replacing them if necessary. Smooth rotors are less likely to cause brake squeaks.
- Inspect the Brake Hardware: Check the brake hardware, such as clips, shims, and springs, for damage or wear. Replacing damaged hardware can help prevent squeaking.
- Proper Bedding-in: After any brake maintenance or replacement, follow the manufacturer’s instructions for proper bedding-in or breaking-in of the new brake pads and rotors. This process ensures that the components wear in evenly and reduces the likelihood of squeaking.
If squeaking persists despite these measures, it may be a sign of an underlying issue, and it’s advisable to have your brakes inspected by a qualified mechanic.
What causes car brakes to squeak?
As mentioned above, ceramic or metallic pads or moisture can cause pads to squeak. This type of squeaking is usually harmless, says Popular Mechanics. But new brake pads can also squeak because of a foreign object, explains Bockman’s Auto Care. Twigs, pinecones or rocks may get stuck between the brake pad and rotor.
Several factors can cause car brakes to squeak:
- Brake Dust: Accumulation of brake dust on the brake components can lead to squeaking.
- Worn Brake Pads: When brake pads wear down, their backing plates can come into contact with the rotors, resulting in squeaking.
- Uneven Brake Pad Wear: Uneven wear of brake pads can cause vibrations and squeaks.
- Rotor Irregularities: Scoring, warping, or rough spots on brake rotors can lead to noise when the brake pads contact them.
- Lack of Lubrication: Insufficient or improper lubrication of the brake components can contribute to squeaking.
- Brake Caliper Issues: Sticking or malfunctioning brake calipers can cause uneven pressure on the brake pads, leading to squeaking.
Can I spray WD40 on my brakes to stop squeaking?
WD40 is a chemical lubricant and rust inhibitor meaning it acts as an oily film over components reducing friction. Now sure, WD40 will stop the squeak but you will also glaze the disc, meaning you will need your discs to be machined or replaced due to contamination.
No, you should not spray WD-40 or any similar lubricants on your brake components to stop squeaking. WD-40 is not designed for use on brake parts and can be harmful. Instead, use a specialized brake lubricant or high-temperature grease applied to the back of the brake pads. This will help reduce friction and noise without compromising braking performance.
Is it OK to drive with squeaky brakes?
It’s not illegal to drive with squeaky brakes, but it could be a roadworthiness concern. If you are due for a new roadworthy certificate or if your car’s registration is due, brakes are one of the things that could require repairs, as they’re one of the most important parts of your car.
While it is generally safe to drive with squeaky brakes, it’s essential to address the issue promptly. Squeaking brakes are often a sign of an underlying problem, such as worn brake pads or irregularities in the braking system. Ignoring these issues can lead to reduced braking performance and potentially unsafe driving conditions. Driving with squeaky brakes can be noisy and irritating to you and others on the road. Therefore, it’s advisable to inspect and address the cause of the squeaking as soon as possible to ensure your safety and driving comfort.
Can you fix a squeaky brake pedal?
Dry brake pedal joints: Sometimes, your car’s brakes will squeak when they’re not lubricated enough. To fix the issue, you’ll need to identify the part of the brake that’s squealing and lubricate or grease the area.
Yes, you can often fix a squeaky brake pedal, but it’s essential to determine the underlying cause first. The squeaking may originate from various sources, including the brake pedal itself, the brake master cylinder, or the brake booster. Here are some steps to address a squeaky brake pedal:
- Brake Pedal Lubrication: If the squeaking is coming from the brake pedal pivot points, applying a silicone-based lubricant or a specialized brake pedal lubricant can help. Ensure that the lubricant is applied sparingly and does not reach the brake pedal pad or the brake pedal sensor, as excessive lubrication can affect pedal grip and sensor performance.
- Master Cylinder Inspection: If the squeaking persists after lubricating the pedal, the issue may be within the brake master cylinder. Inspect the master cylinder for leaks, damage, or worn seals. A malfunctioning master cylinder may require replacement.
- Brake Booster Examination: Squeaking can also result from issues with the brake booster, which amplifies brake pedal force. Check for loose or damaged components in the brake booster assembly. If needed, consult a mechanic for a thorough inspection and potential replacement.
Keep in mind that addressing a squeaky brake pedal should be done with caution, as the brake system’s safety is paramount. If you are unsure about the cause or how to fix it, it’s advisable to seek professional assistance from a qualified mechanic to ensure the braking system’s proper function and safety.
Why do expensive brakes squeak?
High performance braking systems often have larger brake pads, and so the vibrations mentioned above can be greater. The materials also play a part in the squealing sound.
Expensive or high-performance brake components can also squeak, just like standard brake parts. The cost of the brakes does not necessarily determine whether they will squeak. Squeaking brakes can occur for various reasons, regardless of their price tag. Some common factors contributing to squeaking in expensive brakes include:
- Friction Material: Some high-performance brake pads are formulated for superior stopping power, which may result in increased noise during braking. This trade-off in noise for performance is acceptable to many enthusiasts.
- Rotor Type: High-performance brake rotors, such as slotted or drilled rotors, can also produce noise when the brake pads contact their unique surfaces.
- Driving Conditions: Aggressive driving or track use can generate higher temperatures in the braking system, potentially leading to squeaking.
- Brake Dust: Even expensive brakes can accumulate brake dust, which can contribute to squeaking.
To mitigate squeaking in high-performance brake systems, it’s essential to follow proper break-in procedures, use the correct brake pad and rotor combinations, and maintain regular brake maintenance. Keep in mind that some noise may be inherent to high-performance brakes, but it doesn’t necessarily indicate a problem with their functionality.
