What is the main benefit of a drilled brake rotor?

Drilled rotors help to vent gases and heat away from the rotor surface. This can lead to improved braking performance and reduced brake fade, especially during repeated stops or hard braking situations.

Is this rotor a direct replacement for my stock rotor?

This rotor is designed as a direct replacement for the rear left rotor on 1990 and 1991 Mazda 929 models. It should install in place of your original equipment rotor.

What material is this brake rotor made from?

This brake rotor is made from a solid iron casting. Iron is a common and durable material for brake rotors, offering good performance for everyday driving and moderate use.

About this part

Product Details

When you're looking to replace the brake rotors on your 1990 or 1991 Mazda 929, especially if you've noticed some fading during hard braking, a drilled rotor like this one from R1 Concepts can make a difference. This rotor is specifically for the rear left side of your vehicle. Drilled rotors help manage heat buildup, which is crucial for maintaining braking performance, particularly when you're driving in situations that require repeated stops.

This rotor is constructed from a solid iron casting, which is a standard material for good durability. The drilling pattern isn't just for looks; it helps gases and heat escape from the rotor surface. This means less chance of brake fade and a more consistent feel at the pedal, especially after a few miles of spirited driving or when carrying a heavier load. It's a well-built replacement that aims to restore your braking system's effectiveness.
