Step-by-Step Instructions
Follow these steps carefully
1
Raise and support the vehicle
The critical step: ensure the EPB is RELEASED before jacking — the car must be on jack stands with the parking brake disengaged. Rear rotor is 340mm diameter, 22mm thick, vented. Jack from designated points, support with stands, chock front wheels.
🔧 Mechanic's note — Tom Becker
I love the G70's gift: the parking brake is a drum inside the rotor hat, so no scan-tool service mode for a pad job. I just make sure the EPB is released before I start — a dragging shoe will tell me if it isn't.
2
Remove the wheel and caliper
Remove the rear wheels. Remove the caliper bolts and slide the caliper off the bracket — support with wire, don't hang by the hose. Note: the parking brake shoes are inside the rotor hat — when you pull the rotor, you'll see them.
🔧 Mechanic's note — Ray Delgado
I've learned: rotor rusted to the hub? Use the threaded extraction holes — run bolts in and the rotor pops off straight. Beating on it with a hammer is how you damage the parking brake shoes inside.
3
Remove pads and inspect
Remove the old pads from the bracket. The G70 is a performance sedan — expect more aggressive pad compounds and potentially more rotor wear than a standard car. Inspect the parking brake shoes inside the rotor hat while it's off: they should have even lining thickness and the hardware (springs, adjusters) should be intact. These shoes rarely need replacement during a pad job, but inspect them. Clean the caliper bracket abutment surfaces thoroughly. Check slide pins for smooth movement.
4
Retract the piston correctly
Push the piston in evenly. If it resists, check that the parking brake is fully released. Clean the piston boot and inspect for tears — a torn boot lets in moisture and will seize the piston.
5
Install new pads
Install new pads (FMSI D2144) into the cleaned bracket — ensure they slide freely. Install the new rotor (340x22mm vented) over the parking brake shoes — rotate it by hand to confirm the shoes aren't dragging excessively (light contact is normal). Slide the caliper back over the pads. Reinstall caliper bolts to proper torque (consult Genesis service info). Ensure the parking brake shoes are still properly positioned inside the rotor hat before final assembly.
6
Reassemble and verify parking brake
Reinstall wheels, torque lug nuts to spec in star pattern. Lower the vehicle. Pump the brake pedal several times to seat the pads. Test the electronic parking brake: engage and release via the console — it should operate the drum shoes smoothly with no grinding or hanging. Take a test drive: the G70's brakes are performance-oriented, so bed the pads with 5–6 firm stops from 50 mph with cool-down between each. Verify the parking brake holds on an incline. No EPB recalibration is needed for a pad/rotor job on this car.
All Done!
Test your repair before closing everything up. If something doesn't work right, double-check your steps.
⚠️ Common Mistakes to Avoid
- • Not properly securing the vehicle with jack stands before starting the repair.
- • Failing to torque the lug nuts and caliper bolts to the manufacturer's specifications.
- • Not pumping the brake pedal several times to seat the pads.
