Common Problems This Rotor Can Address

• Brake pulsation from a worn or uneven rear rotor
• Reduced braking consistency from heat-affected rotor surfaces
• Corrosion on the rotor hat or exposed metal surfaces
• Rotor replacement needs for rear left Subaru Ascent brake service
• Surface wear that exceeds discard thickness limits

Installation Notes

Verify rear left fitment before installation and confirm rotor dimensions against the vehicle’s brake specifications. Clean the hub mounting surface, inspect pads and caliper hardware for wear, and check rotor thickness after installation to confirm it remains above discard limits. Because this rotor uses a directional brake surface, install it in the correct orientation for the rear left position.

Quality Assurance

This rotor is built with a rust resistant coating and a Geospec Silver Grey hat finish to support long-term appearance and corrosion resistance in brake service. Part number 830-13044L is specified for the 2019-2025 Subaru Ascent rear left application.
