When to replace brake pads, and what it costs in BC

Brake pads are built to warn you before they fail. The trick is knowing which warnings mean "book it this month" and which mean "stop driving and call." Here is how we decide, and what the work costs in BC.

7 signs your brake pads need replacing

1. A high-pitched squeal when you brake. Many pads have a small metal tab, the wear indicator, that touches the rotor when the pad gets thin. It is the cheapest warning you will ever get.
2. Grinding or scraping. This usually means the friction material is gone and metal is rubbing on metal. Every stop now cuts into the rotor.
3. The car takes longer to stop. If you are pressing harder or earlier than you used to, have the pads and the fluid checked.
4. Vibration or pulsing in the pedal or steering wheel. That is usually an uneven rotor surface. Pads are often replaced at the same time.
5. Pulling to one side when braking. One side is working harder than the other, often because of a sticking caliper or uneven pad wear.
6. A brake warning light. Some vehicles have pad sensors that turn on a dash light. On others the light means low fluid or a hydraulic problem.
7. You can see a thin pad. Look through the wheel spokes at the caliper. Thinner than about 3 mm means it is time.

Brake pad thickness: when is it time?

Pad thickness is the clearest answer. Here is how we read the numbers:

So is 4 mm okay? Yes, for a while, but start planning. Is 3 mm okay? It is the point most shops, including ours, recommend replacing. Under 2 mm, you are close to metal on metal, and the bill is about to grow because the rotors usually go with it.

How long do brake pads last?

Most brake pads last between 40,000 and 80,000 km. That is a wide range because pad life depends far more on how and where you drive than on the calendar:

• Stop-and-go traffic wears pads faster than steady highway driving.
• Heavier vehicles and towing put more heat and load into the brakes.
• Hills mean more braking on the way down.
• Front pads usually wear faster than rear pads, because the front brakes do most of the stopping.

That is why we quote brakes per axle: often only the front needs pads.

What brake pad replacement costs in BC

Here are our current prices for the brake work we do most. Every price includes installation and is per axle (both wheels on the front, or both on the back).

A worked example: front pads at $179, plus 5% GST ($8.95) and 7% BC PST ($12.53), comes to $200.48 before any shop-supply or hazmat charge. Your exact price depends on the vehicle, and you get it before we start.

Pads only, or pads and rotors?

Not every brake job needs rotors. Each rotor has a minimum thickness. We measure yours and check them for warping and deep grooves:

• Within spec and smooth: new pads only, or a resurface if the surface is uneven.
• Below spec, warped or badly scored: new rotors with the pads.

This is where waiting costs money. Pads replaced at the squeal usually means a pads-only job from $179 per axle. Pads left until they grind usually means rotors as well, from $399 per axle. If your pads still have life in them, we will tell you that, and you drive away without paying for brakes you do not need.

Why brakes wear differently in the Fraser Valley

Driving around Abbotsford is hard on brakes in a few specific ways:

• Rain for half the year. Wet road grit acts like sandpaper on pads and rotors. A car that sits for a few wet days will show surface rust on the rotors. A light orange film that clears after a few stops is normal. Rust that stays, or a grinding noise that does not go away, is not.
• Hills and long grades. Sumas Mountain, the hills around town, and long descents on trips up the Coquihalla all heat the brakes. Shifting to a lower gear on long downhills takes some of that load off the pads.
• Winter sand and salt. It works into the caliper slides and can make a caliper stick, which wears one pad much faster than the other.

Before a winter highway trip, check road conditions on DriveBC, and if your brakes have been making noise, have them looked at first. ICBC also keeps a good collection of road safety tips for BC drivers.

Same-day brake jobs at Kingdom Auto & Detail

Brakes are one of the jobs we most often turn around the same day. Call (778) 666-6011 with your year, make and model, and we will tell you if we can take you in today and what it is likely to cost. We measure the pads and rotors, show you what we found, and give you the price before any work starts.

If the job is bigger, a courtesy car may be available: book at least 2 days ahead, on jobs over $350 that need 3 or more hours in the shop. You can see the full details on our brake service page. And if your car also pulls to one side when you are not braking, read our guide on how often you need a wheel alignment.
