A recent client brought in her 2021 Tesla Model Y to Speed Projects Laboratory with concerns about squeaky brakes.
The vehicle had 109,777 KM on the odometer, and while brake noise is common on Teslas, especially due to regenerative braking systems, a proper inspection is always critical before assuming pads or rotors require replacement.
Here’s what we found.
Brake Pads Still Healthy – No Replacement Needed
Upon inspection:
- Front brake pads measured 9mm remaining
- Rear brake pads measured 8mm remaining
- Rotors were within safe operating condition
For context, new brake pads typically start around 10–12mm. At 8–9mm, these pads are still in very good condition.
The issue was not worn pads.
Instead, the noise was caused by brake contamination and lack of cleaning — something we commonly see on Tesla vehicles due to regenerative braking.
Why Tesla Brakes Squeak (Even When Pads Are Fine)
Tesla vehicles rely heavily on regenerative braking, which means:
- Friction brakes are used less frequently
- Brake components accumulate surface corrosion
- Pads can glaze
- Dust and debris build up inside calipers
Over time, this causes squeaking and uneven contact — even when plenty of pad material remains.
This is why Tesla recommends periodic brake cleaning and lubrication service.
Brake System Service Performed
Instead of unnecessary pad replacement, we performed a complete Brake System Service, which included:
- Full brake inspection
- Removal and cleaning of brake pads
- Rotor surface cleaning
- Caliper cleaning
- Proper lubrication of slide pins and contact points
- Performance testing
After servicing, braking performance returned to normal and the noise concern was resolved.
This type of maintenance is especially important on electric vehicles like the Tesla Model Y.
Suspension Inspection – Cracked Lower Control Arm Bushings
During our multi-point inspection, we discovered an important issue:
All four lower control arm bushings were cracked.
On higher mileage Teslas (100,000+ KM), this is not uncommon.
Lower control arm bushings are responsible for:
- Maintaining suspension geometry
- Absorbing road vibrations
- Keeping steering stable
- Preventing clunking noises
When bushings crack or deteriorate, drivers may notice:
- Steering looseness
- Uneven tire wear
- Suspension noises
- Reduced handling stability
Although the vehicle was still drivable, we recommended replacing the lower control arms to restore proper suspension integrity.
Preventative suspension maintenance is critical for safety and tire longevity.
Cabin Air Filter Replacement (Every 2 Years)
We also replaced the cabin air filter during this visit.
Tesla recommends replacing the cabin air filter every 2 years.
Over time, filters become clogged with:
- Dust
- Pollen
- Moisture
- Odor-causing bacteria
A fresh cabin air filter improves:
- Interior air quality
- HVAC efficiency
- Cabin odor control
Especially in the Lower Mainland where we experience damp climate conditions, this maintenance item is often overlooked.
Why Regular Inspection Matters on Tesla Vehicles
Many Tesla owners assume:
“No engine = no maintenance.”
While EVs require less drivetrain maintenance, they still require:
- Brake servicing
- Suspension inspections
- Cabin filter replacements
- Cooling system checks
- Alignment checks
At over 109,000 KM, this Model Y is entering the stage where suspension wear components naturally begin to show fatigue.
Catching cracked bushings early prevents more expensive issues later.
