2019 Genesis G70 Brake Upgrade Options

By Core Brake Parts Tech Team — Circleville, OH warehouse

A 2019 Genesis G70 does not need a big brake kit. The car already runs vented discs at all four corners, and cars ordered with the High Performance Brake option carry large-diameter Brembo fixed calipers from the factory, so almost every worthwhile upgrade is a pad-and-rotor decision. Pick the friction compound that matches how you actually drive the car, and step up to a slotted rotor only if you are putting real heat into the brakes you have.

What your 2019 G70 came with

The 2019 G70 owner's manual describes a four-wheel disc system with a pad wear indicator that makes a high pitched warning sound from the front or rear brakes when the pads are worn and new pads are required. Cars with the factory option the manual calls the High Performance Brake are described as having large-diameter Brembo brakes for enhanced braking performance, and the manual specifically says squeal, squeak or groan while braking is normal on that system, as are circle patterns on the disc surface.

Two details on the car change which parts you order. First, the Brembo cars and the standard-caliper cars use different pad shapes and different rotor diameters, so the part you need depends on the caliper, not the badge on the trunk. Second, the 2019 G70 was built with two different parking brake designs, both listed in the manual as equipment-dependent: a foot-operated parking brake and an Electronic Parking Brake. That matters when the rear pads come out.

Fluid is simple. The manual specifies hydraulic brake and clutch fluid conforming to DOT 3 or DOT 4, and the specifications table lists FMVSS116 DOT-3 or DOT-4 with a system volume of 0.74 to 0.85 US quarts (0.7 to 0.8 liters).

Matching the pad compound to how you drive

This is where most of the gain is. EBC publishes what each compound is built for, and the honest answer is that the best pad for a G70 depends entirely on whether you want less dust, more bite, or brakes that survive a track session.

Read that table against your own complaint. Wheels black after a week of commuting points at EBC Redstuff front pads for the G70 2.0T. Wanting a firmer first hit of the pedal on back roads points at the Greenstuff 2000 front set for Brembo-equipped cars. Fast street driving with the occasional spirited run is the Yellowstuff front set case. Only step up to Bluestuff NDX front pads if you actually run track days, and pair them with the matching Bluestuff NDX rear set so the balance front to rear stays sane.

One rule applies to all four: change both pads on an axle at the same time, and do not mix compounds side to side. Browse the full range of brake pads if you want to compare fitments before you commit.

When a slotted rotor earns its place

A rotor upgrade solves a heat problem, not a grip problem. EBC's BSD disc is cast from G3000 grey iron, heat-treated, precision balanced and given a corrosion-resistant finish. Its bi-directional blade slot design is described as evacuating hot gases to keep the pads cooler and wearing evenly, with overlapping slot geometry intended to minimize the wind noise that slotted rotors are known for. EBC's stated aim for the design is a disc that stops faster and runs cooler with less thermal distortion.

In practice, that is worth paying for if your G70 gives you a long pedal after repeated hard stops from highway speed, or if you have already glazed a set of pads. The BSD V-slot front rotor set for Brembo cars and the matching BSD rear rotors keep the factory diameter and hat, so nothing else on the car has to change.

If your only symptom is a steering wheel that shudders under braking from highway speed, that is usually uneven pad material transfer or thickness variation in the disc rather than a heat capacity problem. Fresh discs and a correct bed-in procedure fix it; a slotted disc is optional. Compare the available brake rotors for the car before deciding.

Three things to check before you order

Which caliper you have. Look at the front caliper through the wheel. A fixed caliper with multiple pistons and Brembo cast into the body is the High Performance Brake, and it takes a different pad and a larger rotor than a standard car. Ordering by trim name alone is how people end up with parts that do not fit.

Which parking brake you have. The manual lists both a foot-operated parking brake and an Electronic Parking Brake as equipment-dependent. If your car has the EPB, the system has to be put into its service mode with a scan tool, following the factory procedure, before you work on the rear brakes. Find out which one you have before the car is on stands.

Open recalls. NHTSA lists recall 21V161000 covering 2019 through 2021 Genesis G70 vehicles for an ABS module malfunction and short circuit risk, with a remedy of replacing the ABS module fuse and a recommendation to park outside until the repair is done. Run your VIN before you spend money on friction parts.

What to replace at the same time

Pads and rotors are the job, but a few things go with them. Replace the hardware, clips and shims rather than reusing tired ones, and clean and re-lubricate the caliper slide pins on any floating caliper. Inspect the flexible hoses and hard lines while the wheel is off; the maintenance schedule calls for brake lines, hoses and connections to be inspected at every service interval, which on the normal schedule means every 12 months or 6,000 miles.

Brake fluid is the item most G70 owners skip. The normal maintenance schedule has the brake and clutch fluid inspected every 24 months or 12,000 miles, and fluid that has absorbed moisture lowers the boiling point exactly when a performance pad is asking the most of it. If you are moving to Yellowstuff or Bluestuff NDX, fresh fluid to the specified DOT rating is part of the upgrade, not an extra.

Worth knowing: the Genesis New Vehicle Limited Warranty treats brake pads and linings as a normal maintenance item, warranted only for 12 months or 12,000 miles and excluded once they are simply worn. These are consumables you own.

How hard is the job

A pad and rotor change on one axle is a normal weekend job for someone with a torque wrench, jack stands and a repair procedure in front of them. Budget a couple of hours per axle the first time. Torque every caliper bracket bolt, caliper bolt and wheel fastener to the value in the factory service manual rather than guessing, and never let the caliper hang from its hose.

Bedding matters more than most people expect with these compounds. EBC's own guidance is that Yellowstuff beds in over the first 100 to 200 miles of ordinary urban driving, and that even Bluestuff NDX, with its reduced bed-in time, should see 200 miles of gently increasing brake use in a safe environment before hard work. Skipping that step is the usual reason a new set of performance pads feels wooden or squeals more than it should.

Finally, keep to the inspection interval. The G70 normal maintenance schedule has the front brake disc, pads and calipers and the rear brake disc and pads inspected every 12 months or 6,000 miles, and calls for more frequent inspection under severe usage conditions such as heavy stop-and-go traffic or mountainous driving.

Frequently Asked Questions

Can I fit Brembo-application pads to a non-Brembo G70?

No. The Brembo fixed caliper and the standard caliper take different pad shapes and different rotor sizes, and EBC lists separate part numbers for each. Identify the caliper on the car, then order to it.

Do I have to replace the rotors when I change pads?

Not always, but the discs have to be within the factory thickness and runout specification and free of scoring and heat marks. The owner's manual maintenance description is to check the pads for excessive wear, the discs for runout and wear, and the calipers for fluid leakage. If a disc fails any of those, replace it rather than trying to bed a new pad onto a bad surface.

Which EBC compound is the best all-round choice for a daily-driven G70?

For a car that mostly commutes, Redstuff is the pick because EBC builds it specifically as the low dust premium street pad. If you want a firmer initial bite and can live with a little more dust, Greenstuff 2000 is the direct-replacement sport option. Yellowstuff and Bluestuff NDX are for drivers who are genuinely asking more of the brakes.

Will performance pads make my brakes squeal?

Some noise is normal, and Genesis says so. The owner's manual states that squeal, squeak or groan while braking is normal on the High Performance Brake system. What is not normal is a continuous grinding or continuous squeal, which the manual says may mean the brake lining is worn out and should be checked.

What brake fluid does the 2019 G70 take?

Hydraulic brake and clutch fluid conforming to DOT 3 or DOT 4, listed in the specifications as FMVSS116 DOT-3 or DOT-4, with a system volume of 0.74 to 0.85 US quarts. Use what the manual specifies and keep the reservoir between the MIN and MAX marks.

Is a slotted rotor louder than a plain one?

Slotted discs can generate wind noise, which is why EBC uses an overlapping slot geometry on the BSD disc specifically to minimize it. If quiet running matters more to you than heat management, a plain replacement disc with a good street pad is the safer choice.
