Why Do My Brakes Smell Hot?
Burn marks on the brake rotors are a sure sign the brakes are getting cooked.
Ever hopped out of the car at Chartwell, or at the supermarket carpark in Frankton, and caught a strong, hot, almost burning smell coming from your wheels? You’re not alone. Brakes smelling burnt or just “hot” is something we see all the time at the workshop, especially with the stop-start chaos through Hamilton’s Victoria Street or constantly braking on Peachgrove Road during school pick-up times.
Let’s break down why your brakes might be putting out that weird smell:
- Overheated Brakes: Maybe you’ve been crawling in traffic down Ulster Street, or had to ride the brakes going down Hakarimata Road into Ngaruawahia. All that braking creates serious heat. Too much heat, and you’ll get that telltale hot smell.
- Stuck Caliper or Pads: Common on older Mazdas and Volkswagens, but we see it on all sorts—Toyota Auris, Honda Fits, even the odd Peugeot. If a brake caliper gets sticky (often after a bit of track build-up from summer dust or those deep winter puddles in Rototuna), it can keep rubbing the brake the whole time you’re driving. Cue the burning smell.
- Worn Out Pads: Had a customer from Cambridge in her Nissan Serena—her pads wore right through, metal on metal, and the whole car reeked. If you leave your pads too long, they get thin, then they start grinding, and it gets nasty (for your nose, and your rotors).
- Leaking Brake Fluid: Hot and stinky, this one. If a seal lets go and a bit of fluid dribbles onto the hot rotor or pad, you get a chemical smell. Not just stinky—dangerous, too.
- Seized Slides or Pistons: Kias, Subaru Imprezas, even an MG we had in from Morrinsville last week—when part of your brakes gets locked up, it’s like driving around with your handbrake half on all day. More friction, more heat, more smell!
- Wrong Pads or Dodgy Installation: Sometimes someone’s fitted cheap pads, or even the wrong ones for the car (seen it a bunch on imports, especially from Japan or the UK). Or, bits just weren’t put back right.
Here’s a handy guide for making your brakes last longer
Should You Keep Driving If Your Brakes Smell?
Honestly mate, if you reckon something’s not right—best not to take chances. Smelling burning brakes as you pull out of Pirongia or up the hill from Taupiri is your car telling you something needs attention. Not getting it checked can turn a small issue into a big, expensive problem. We’ve seen people come in after putting it off and ended up with warped rotors or cooked brake fluid, and then you’re up for a lot more than a simple service. If you’re after car service Hamilton or need a quick WOF Hamilton, pop in—one of our techs can take a look and keep you safe.
Driving Habits That Stoke the Heat
Heavy Feet or Riding the Brakes
If you’re constantly stomping on the pedal or hovering with your foot on the brake—especially through town or navigating those mystery potholes out in Te Kowhai and all the speed humps down Nawton—you’ll make your brakes work overtime. More heat means more smell and more wear.
Driving With the Handbrake On
Easy mistake. Happens to everyone—one of our techs reckons he’s done it twice. If you leave the handbrake (parking brake) on, even just a bit, especially in an automatic (like a Hyundai i45 or a Suzuki Swift), you’ll cook your rear brakes super fast. Always check before you head off!
New Pads or Discs? Bit of Smell is Normal—for a Little While
Got new brakes fitted recently, maybe on your Audi Q2 or Toyota Estima? You might get a whiff of something hot for a few hours. That’s just the new pads bedding in and the resin curing—totally normal. But if it drags on, or the car feels weird, don’t muck around, get it checked.
