Mazda 3The brake system in a Mazda 3 requires regular maintenance for safe operation. Learn more about how the disc brakes in this make and model work, which Mazda 3 parts you will need to complete a brake job and answers to common questions such as when do you need new brakes.

How Do Mazda 3 Brakes Work?

Disc brake systems are standard in every Mazda 3 year model from 2003 through the current year. The main disc brake components include brake pads, calipers that contain pistons and rotors that are mounted to hubs.

The brake master cylinder converts the mechanical force of depressing the brake pedal into hydraulic pressure. Hydraulic fluid flows through brake lines, engaging the pistons at each wheel, activating the calipers and creating friction between pads and rotors.

What Parts Do You Need for a Brake Job?

A brake job will require Mazda 3 brake pads and may either involve using a brake lathe to resurface rotors or installing replacement rotors. If it is necessary to bleed brakes, you will also need brake fluid. Tools such as a jack, jack stand, lug nut wrench and a brake caliper piston tool or C clamp are helpful for accessing and removing and reinstalling hardware and parts.

Start by lifting and supporting the vehicle to check the condition of inner and outer brake pads and the rotors. In addition to replacing these components, it may be necessary to clean and lubricate caliper sliders, retainers and spring clips. Brake pad guide pins and retainer pins may also need to be cleaned. Replace any damaged components.

How Do You Maintain Mazda 3 Brakes?

Always check the brake fluid level during oil changes. A translucent plastic reservoir makes it possible to see the fluid level without opening the cap. Avoid removing the cap unless you are replacing fluid to limit exposure of the hydraulic system to air and moisture. This fluid should only need to be changed about every five years.

Replace brake pads every 50,000 miles and inspect the condition of rotors and calipers to ensure that a brake system continues to function properly. Any signs of uneven wear on pads or damage to the rotor that cannot be smoothed out on a brake lathe indicate the need for more extensive brake repairs and part replacements.

When Do You Need New Brakes?

If any brake components have sustained damage, you should replace these parts sooner rather than later. Every component in a disc brake system is connected, and damage to one part is likely to affect the entire system.

Pay particular attention to any sounds and sensations brakes make while driving a Mazda 3. Squealing or grinding noises and sensations of pulling or shuddering can indicate brake problems. The illumination of the brake warning light on the dashboard is a clear indication this system requires maintenance.

It is important to maintain Mazda 3 brakes. Most brake pads last about 50,000 miles, depending on driving habits. Regular brake jobs and fluid checks can insure that this safety system will continue to function reliably.
