Detailed Product Description

The Raybestos 681781PER disc brake rotor is a vented rotor featuring a drum-in-hat design, which integrates the parking brake drum within the rotor itself. This design is common for many Ford Transit models, providing both braking and parking brake functionality in one component. The rotor’s 12.126-inch outside diameter and 1.303-inch nominal thickness deliver a substantial braking surface area, while the discard thickness of 1.181 inches indicates when the rotor should be replaced to maintain safe braking performance. The vented construction helps dissipate heat during braking, reducing the risk of brake fade under heavy use.

Specialty - Street Performance; S-Groove Technology Line

This rotor is part of the Raybestos Specialty - Street Performance; S-Groove Technology line, which focuses on delivering enhanced braking performance for street-driven vehicles. The S-Groove design aids in improved pad bite and helps channel away dust and gases generated during braking. This product line is tailored for drivers who require dependable stopping power and rotor durability under typical street driving conditions.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Ford Transit and E-Transit models
• Addresses brake noise and vibration issues caused by uneven rotor surfaces
• Restores braking efficiency lost due to rotor thickness below discard limits
• Solves overheating problems with vented rotor design for heat dissipation
• Integrates parking brake function with drum-in-hat rotor design

Installation Notes and Tips

• Ensure rotor thickness is measured before installation to confirm discard limits
• Clean mounting surfaces and hub to prevent rotor runout
• Torque mounting bolts to manufacturer specifications for secure fitment
• Inspect brake pads and replace if worn to maintain optimal braking performance
• Check parking brake components when replacing drum-in-hat rotors
