The Cadillac DTS (DeVille Touring Sedan), introduced in 2006, features a disc brake system with both front and rear brakes. The vehicle utilizes hydraulic brakes and offers two different caliper/rotor combinations: J55 (heavy-duty) and JL9 (standard). The J55 system uses larger diameter and thicker rotors, while the JL9 system utilizes a smaller rotor. 8-lug versions of the J55 system are used for limos.

The DTS models have two brake systems: J55 and JL9, which can be identified by rotor size and casting on the calipers.
GM recommends using high-quality brake pads that can handle the heat generated during braking due to the DTS's larger size.
These components help align and secure the disc brake caliper and ensure structural support for the brake pads to the rotor.
Rotors are made of cast iron and are designed for durability and reliable performance.
The brake pads are typically ceramic for quieter braking, less dust, and smooth, stable performance.
Brake kits for the DTS may include front and rear rotors with ceramic pads, hardware, and calipers.
Brake rotors with drilled and slotted designs are used to improve heat dissipation, reduce brake fade, and ensure consistent stopping power.
The DTS's braking system is designed to handle the heat generated during braking, especially on steep grades.
Some customers may experience brake noise or pulsation, which can be addressed by using updated brake pad formulations or high-quality aftermarket pads.
Brake pads should be replaced when the friction surface wears to within 0.76 mm (0.030 in) of the mounting plates.
Caliper inspection should include checking for any debris or rust buildup on slide pins, which can cause resistance and affect braking performance.
Complete brake kits are available and should be installed according to manufacturer instructions to ensure proper fit and balanced braking.
J55 and JL9 are RPO codes (Regular Production Options) that identify the specific brake system on the vehicle.
Brake kits and components should be specifically designed for the Cadillac DTS to ensure proper compatibility and reliability.
It is recommended to have brake replacements and repairs performed by a qualified mechanic to ensure proper installation and functionality.
