What goes wrong
HSV Clubsport and GTS models use large Brembo multi-piston front calipers with sliding guide pins that corrode inside their bores when dust boots split or pins are not greased at service intervals. Seized guide pins cause uneven pad wear, brake pull, and caliper drag that overheats the disc on the affected side. The large caliper size and HSV-specific fitment make replacement more expensive than standard Commodore brakes.
What you would notice
- Brake pull to one side during normal braking
- Uneven pad wear — inner pad worn significantly more than outer on the same caliper
- Caliper running noticeably hotter than the opposite side after driving
- Brake drag sensation at low speed
- Grinding or uneven feel through brake pedal
How to check it
Where to look. Front brake calipers, caliper guide pin bores at inner and outer pin locations
Compare front brake pad thickness on both sides of each caliper. Attempt to extract guide pins — corroded pins resist movement or cannot be removed. Inspect dust boots for splits or tears. After a gentle drive, check disc temperature on each front corner by hovering a hand near the disc face.
What it costs to put right
$400 to $1,200 at New Zealand independent workshop rates. That is for this job on its own, not for the car.
Ask the seller
- “Have the brake calipers been serviced and guide pins replaced?”
- “Any brake pull or uneven pedal feel?”
- “When were brake pads and rotors last replaced?”
