Brakes Squealing, Grinding or ABS Light On?

By the Radman Auto Repair team, independent auto repair in Etobicoke since 1999 · Updated October 2026

Brakes tell you when something is wrong: a squeal, a grind, a pulse in the pedal or an amber ABS light on the dash. Some of those noises are harmless and some mean you should stop driving soon. Radman Auto Repair diagnoses brake noise and ABS warnings in Etobicoke, measures the pads and rotors, and fixes the cause instead of slapping on pads.

Brakes Squealing: Common Causes

Brakes Grinding: Stop Soon

Grinding that comes with a pull to one side, a burning smell or a hot wheel usually means a dragging brake. See why catching caliper problems early saves money and brake pulsation diagnosis.

ABS Light On: What It Means

The ABS (anti-lock braking system) light comes on when the system finds a fault and turns anti-lock off. Your brakes still stop the car, but the wheels can lock up in an emergency stop on ice or rain. Traction and stability control often switch off at the same time, so you may see those lights too.

• Wheel speed sensor: the most common cause. Sensors at each wheel are exposed to salt, water and debris.
• Sensor wiring or tone ring: corroded connectors, chafed wires or a cracked or rusted tone ring on the hub or axle.
• Worn wheel bearing: on many cars the sensor reads from the bearing, so a loose bearing upsets the signal. See wheel bearing noise.
• Low brake fluid: often with the red BRAKE light. See brake fluid flush.
• ABS module, pump or fuse: less common, and confirmed by testing before anything is replaced.

How We Diagnose and Repair Brakes

1. Road test to hear the noise, feel the pedal and check for pulling.
2. Measure, do not guess pad thickness on both sides, rotor thickness and runout, and caliper movement.
3. Scan the ABS system read the stored codes and live wheel speed data to find the corner at fault.
4. Check the fluid level and condition; brake fluid absorbs water over time.
5. Repair properly quality pads, rotors when needed, cleaned and lubricated hardware, and sensors or wiring repaired at the source.
6. Test again road test and confirm the warning lights are off.

Alex is a great guy. He took the time to respond by phone and walk me through my options for my Tesla Model Y 2024 and gave me his perspectives as a Tesla owner. Top recommendation in my books for the Toronto area.

I cannot say enough good things about Livio and the team at Radman Auto Repair in Rexdale. We brought in my son’s 2015 Mitsubishi Lancer because the A/C was malfunctioning. We had already been to two other shops, paid for diagnostics, and received different explanations, so we were frustrated and unsure what to do next. Livio was outstanding. He listened carefully, looked at the issue, and explained everything clearly and in detail in a way that actually made sense. He was able to narrow down what was going on within minutes, without guessing, pressure, or recommending unnecessary work. What really stood out was that he did not charge us another diagnostic fee after learning we had already paid for two separate diagnoses. Even better, the work was completed the same day, which was a huge relief. It is rare to find a mechanic who is knowledgeable, honest, patient, efficient, and genuinely focused on helping customers understand the real issue before they spend money on repairs. Livio truly gets it. We are so happy we found Radman Auto Repair and would highly recommend Livio and his team to anyone looking for trustworthy, skilled, and customer-focused service..

My 2015 Honda CR-V was blowing hot air and making noise when the A/C was on. The Compressor and Expansion valve needed replacement due to metal debris in the system. I rarely write reviews, but I felt it would be wrong not to appreciate Radman for their service, especially after what I went through before finding them. I’m writing this one month after the repair because I wanted to test my A/C on multiple long trips before recommending them. One thing I learned from this experience is that many mechanics know how to replace parts, but very *few follow the right procedures* and perform the proper checks. I initially went for a cheaper repair at a local mechanic. The problem came back, and afterward he didn’t seem to know what to do next. I found Radman through Google reviews without any personal recommendation, so I was taking a chance. They properly diagnosed the issue, explained everything clearly before starting the work, didn’t exaggerate the problem, and charged me a reasonable price. A/C issues can be complicated but they answered all my questions and I honestly haven’t had such a good and detailed conversation with a mechanic in the GTA about an A/C problem. Their knowledge and experience with A/C systems really stood out. I also had a catalytic converter issue. Another mechanic simply recommended replacing it, which would have cost at least $2,000. Radman explained that considering the age and condition of my 2015 CR-V, such an expensive replacement might not make sense. They gave me the replacement cost but also suggested trying Cataclean first. I tried it, and so far I haven’t had any issues. After a month and several long trips, my A/C is still working well. It’s rare to find this combination of knowledge, transparency, and honesty. Thank you, Radman, for the knowledgeable and honest service. I genuinely appreciate it.

I fix my cars myself but I always go to Radman for AC work. Been coming here for years and they do great work and are fairly priced. The guys are honest and reliable. Very clean waiting room too!

Finding a mechanic who actually understands EVs and is completely trustworthy is hard to come by, but ⁠Radman Repair is excellent. The service was top-notch, they explained everything to me with so much patience, and the overall experience was a 10/10. 100% recommended!
