All 1 Known Issues
On the 2021-2025 Acura TLX, tLX models equipped with the A-Spec or Type S brake package experience persistent brake squeal during light braking and premature inner pad wear on the front calipers. The sport-oriented pad compound generates significant noise at low speeds, and the sliding caliper pins seize from corrosion in regions with road salt.
Common Symptoms
- High-pitched squeal during light braking
- Inner pad wearing faster than outer pad
- Grinding noise after rain or car wash
- Brake dust buildup heavier on one wheel
How to Fix
Clean and re-lubricate the caliper slide pins with high-temperature silicone grease. Replace the OEM pads with a ceramic compound pad that offers similar performance with less noise. Apply anti-squeal shims if missing from the factory. Inspect and replace caliper bracket hardware if corroded.
