Understanding Your Car’s Brake System: Safety, Maintenance & Common Issues

Your car’s brake system is one of the most critical components for safety and performance. Whether driving in Kelowna or on long road trips, proper brake maintenance helps prevent accidents and costly repairs. Here’s everything you need to know about how your brakes work and how to keep them in top condition.

How Your Brake System Works

  1. Brake Pedal – The First Step in Stopping Your Car
  • When you press the brake pedal, it sends force to the master cylinder, which then pushes brake fluid through the system.
  • This fluid activates the calipers or wheel cylinders, helping your car slow down.
  • The pedal also has a switch that turns on your brake lights to signal to other drivers.
  1. Brake Pads & Rotors – Creating Friction to Stop Your Car
  • Most cars have disc brakes on the front wheels and often on the rear too. Some vehicles still use drum brakes in the rear.
  • The brake caliper uses hydraulic pressure to push brake pads against the rotor, creating friction that slows your wheels.
  • Brake pads are designed to withstand high temperatures and pressure, while rotors help dissipate heat.

Common Brake Problems & How to Fix Them

Brake Pad Wear – Signs You Need a Replacement

Squeaking or Grinding – Worn-out pads can make noise when braking.
Increased Stopping Distance – If your car takes longer to stop, it’s time to check your brakes.
Warning Indicators – Some brake pads have built-in metal tabs that signal wear; others must be checked manually.

Solution: Have your brake pads inspected every 6 months. Replacing pads early prevents damage to rotors and ensures safe braking.

Warped Rotors – Causes & Fixes

Pulsing Sensation – If your brake pedal vibrates when stopping, your rotors may be warped.
Overheating – Rotors warp due to excessive heat or improper wheel installation.
Thin Rotors – Many modern vehicles have thinner rotors that warp faster.

Solution: Some rotors can be resurfaced using a lathe, but if too thin, replacement is necessary. Always ensure lug nuts are evenly torqued to prevent future warping.

Brake System Maintenance – Prevent Costly Repairs

Don’t “ride” your brakes – Apply firm pressure, then release to allow cooling.
Downshift when driving downhill – This reduces brake stress but should only be done in safe road conditions.
Keep brakes clean – Use brake cleaner to remove dust and debris for better performance.

What to Discuss with Your Mechanic

Beware of “low-price” brake jobs – Some shops upsell unnecessary repairs. Stick with a trusted mechanic.
Ask for proof of replaced parts – Insist on seeing the old brake pads to ensure replacements were needed.
Use anti-squeak compound – Applying paste or spray prevents annoying brake noises.
Proper lug nut torque is essential – Uneven tightening can cause rotor warping. Avoid shops that only use impact wrenches without torque control.

Lifetime Brake Pads – Worth It or Not?

  • Pros: Some brands offer lifetime warranties, meaning free replacements when pads wear out.
  • Cons: Harder pads wear down rotors faster, leading to costly replacements.

Tip: If keeping your car long-term, weigh the cost of rotor replacements vs. standard brake pads.

Final Thoughts – Keep Your Family Safe

Your brakes are essential for safe driving. Routine inspections, preventive maintenance, and using a trustworthy mechanic can help ensure optimal braking performance and avoid expensive repairs.
