The drum brake
A Maybach car is the first to use the modern drum brake, shoes pressing out against a spinning drum.

Your brakes
are talking
Brakes rarely fail without warning. They squeal, grind, shake or go soft first. Tap what you're noticing and we'll match the job to it.

Grinding
Metal on metal. The pad may be gone and the rotor is taking the damage. Book soon.
Pads and rotors03FEEL
Pulsing pedal
A pedal or wheel that shakes when you stop often points to uneven rotors. Tell the shop when it happens. BAR guide
Pads and rotors04FEEL
Pulls to one side
The car drifts left or right when you brake. A sticking caliper or uneven wear can do it.
Inspection05FEEL
Soft or sinking pedal
Air or a leak in the brake fluid can make the pedal sink. Get it checked before you drive far.
Inspection06SEE
Brake light on
Low fluid, worn pads or an ABS fault can turn it on. Your owner's manual says what yours means.
Inspection07SMELL
Burning smell
A hot, sharp smell after hills or hard stops can mean overheated brakes or a caliper that drags.
Inspection08KNOW
Just bought it used
You don't know how the last owner drove. An inspection tells you what's left on the pads and rotors.

Foot to fluid
to friction
- 1
You press the pedal
The pedal multiplies your foot's push and sends it into the master cylinder.
- 2
Fluid carries the force
Brake fluid doesn't squeeze down, so the push reaches every wheel at once. Hydraulic brakes spread through cars from the mid 1930s.
- 3
Calipers clamp the rotors
At each wheel a caliper squeezes two pads against a spinning rotor.
- 4
Motion becomes heat
Friction turns your speed into heat. Pads and rotors wear a little on every stop, and fluid can absorb moisture over time, so your owner's manual lists when to check each.

The colors of stopping
Three reds
Red means stop on every road in the country. On brakes, it shows up three ways.
BY LAWStop lamp red
Federal Motor Vehicle Safety Standard 108 sets the rules for car lamps, and stop lamps have to be red. eCFR
BY CHOICECaliper red
Painted red calipers became the badge of performance brakes. You can spot them through the wheel spokes.
BY PHYSICSHeat red
Every stop turns speed into heat. Brake hard enough, like a race car into a corner, and the rotors glow.
The history
From drums
to discs
Copper rode in with the first disc brake in 1902. California pushed it out in 2025. Swipe through what happened in between.
The first disc
Frederick Lanchester patents a caliper disc brake. Its pads are copper, which wears fast on the rough roads of the day.
Renault's patent
Louis Renault patents the drum brake principle. Drums stay on most cars for the next fifty years.
Hydraulics
From the mid 1930s, fluid pressure in small wheel cylinders works the brakes instead of rods and cables.
Discs win Le Mans
A Jaguar C-Type wins the 24 Hours of Le Mans. It's the only car in the race with disc brakes, developed with Dunlop.
Discs for everyone
The Citroën DS becomes the first sustained mass production use of modern disc brakes.
Anti-lock brakes
Bosch's electronic four wheel ABS arrives as an option on Mercedes-Benz cars. Wheels keep turning, so you can still steer.
California's pad law
The state passes a law to cut copper in brake pads, because brake dust washes into waterways and copper is toxic to aquatic life.
ABS for every car
NHTSA requires anti-lock brakes along with electronic stability control on new US light vehicles from September 2012.
Copper nearly gone
Pads sold in California must be under 0.5% copper. Boxes that meet it carry an N mark.

Good to know
Brake questions
How do I know I need brakes?
Squealing, grinding, a pulsing or soft pedal, pulling to one side when you stop, a burning smell or a brake warning light. If you're not sure, ask for an inspection.
Pads only, or pads and rotors?
It depends on the rotors. The shop measures their thickness and checks for scoring or uneven wear, then tells you whether they can stay. Ask for it in the written estimate.
How long do brake pads last?
It varies a lot with the car, the pads and how you drive. Stop and go traffic and hills wear them faster. An inspection tells you how much is left.
Is it safe to drive with grinding brakes?
Grinding usually means metal on metal, which damages rotors and can weaken your stops. Book soon. If the pedal sinks or the brake light stays on, have it checked before you drive.
How often should brake fluid be changed?
Brake fluid can absorb moisture over time. Your owner's manual lists the interval for your car, and a shop can test the fluid during an inspection.
Do EVs and hybrids need brake work?
Yes. Regenerative braking does a lot of the slowing, so pads often wear slower, but calipers, rotors and fluid still need checks.
Do I get a written estimate?
In California, a repair shop must give you a written estimate before doing any work and get your permission before charging more than that estimate, according to the Bureau of Automotive Repair.
The DMV wants a brake and lamp certificate. What now?
The Bureau of Automotive Repair now issues a vehicle safety systems inspection certificate, and some DMV paperwork may still use the old name. Check the BAR safety page for licensed stations.
How much does a brake job cost?
Each shop sets its own price based on your car and what it needs. Shops quote you through Lokuli, so you can compare before you book.
