Parts for your 2020 Holden Commodore-Pedal pads

2020 Holden Commodore pedal pads — what they do and when to replace them

Based on the Holden ZB Commodore Workshop Manual (GM Service Information), the GM Global Electronic Parts Catalogue, and Opel/Insignia B parts listings, the 2020 Holden Commodore is fitted with a removable rubber brake pedal pad on automatic models. The accelerator is an electronic pedal with an integrated tread (no separate pad), there’s no clutch pedal offered on ZB Commodore for Australia or New Zealand markets, and the vehicle uses an electronic park brake switch. So “pedal pads” are relevant to this model specifically as the brake pedal rubber cover.

The brake pedal pad’s job is simple but critical: it gives the driver reliable, non-slip grip under all conditions, helps damp vibration, and protects the metal pedal plate from wear. On wet mornings, after a beach run, or with a bit of dust on the soles, that grippy rubber is what keeps braking feel consistent and safe. It also helps the car meet local roadworthy/WOF expectations for pedal condition and slip resistance.

As part of regular servicing, the brake pedal pad should be checked for hardening, glazing, cracks, tears, or edges that have rolled off the pedal plate. If it’s shiny, slippery, or starting to split, it’s time to swap it. Most owners will find it’s a quick, low-cost maintenance item that restores a confident pedal feel straight away.

• Replace the pad if: it’s slippery when wet, visibly cracked or torn, the lip won’t stay seated, or the surface has gone hard and glossy.

Replacement is a straightforward DIY fit: ease the old pad off the pedal plate, clean the metal face with a mild cleaner, then warm the new pad slightly (a few minutes in warm water helps). Hook the top lip over first and work the pad down until the rubber lip fully surrounds the plate. Press around all edges to confirm it’s seated. Test the pedal feel before driving.

For the 2020 Commodore, use a genuine GM/Opel-style brake pedal pad or a quality aftermarket equivalent designed for ZB/Insignia B automatic models. Avoid stick-on grip tapes or universal pads that can shift underfoot. If the accelerator surface is worn, the remedy is replacement of the pedal assembly rather than a pad, but that’s uncommon.

FAQs

Does the 2020 Holden Commodore have a clutch pedal pad?
No. The ZB Commodore sold in Australia and New Zealand was automatic-only, so there’s no clutch pedal and no clutch pad. The only serviceable pedal pad on these cars is the rubber brake pedal cover.

Which brake pedal pad fits a 2020 Commodore?
Use a pad specified for Opel Insignia B/Holden ZB automatic models. A Holden/GM parts counter can confirm by VIN via the GM Global EPC. Most trims (2.0T and 3.6 AWD) share the same automatic brake pedal pad, with optional “sports” pedal kits available on some variants.

Can the brake pedal pad be replaced at home?
Yes. It’s a 5–10 minute job with no special tools. Remove the old cover, clean the pedal plate, warm the new pad, and stretch it on, ensuring the lip sits evenly all the way around. Recheck after the first drive to make sure it hasn’t shifted.
