Brake pads are the small friction blocks that squeeze against your rotors to stop your car — and they come in more flavors than you’d expect. The two most common families are ceramic and metallic (with semi-metallic being the most popular metallic variant). They look similar from the outside, but inside, they’re completely different materials…
Flip over most small and mid-size hatchbacks, sedans, and crossovers and you’ll see the same thing in the back: a metal beam running side to side, connecting the two rear wheels. It looks like a solid axle — but it’s not. It’s a torsion beam (also called a twist beam) suspension, and it’s one of…
If your engine were a person, the engine block would be the torso and the cylinder head would be the brain. They’re bolted together for the life of the car, they share a crucial gasket, and they’re often confused with each other — but they do completely different jobs. Whether you’re shopping for a rebuilt…
Walk past a parked car that’s been sitting for a week in the rain and you might notice something alarming: the brake rotors are covered in orange-brown rust. It looks like the brakes have turned to a pile of corrosion, and plenty of drivers panic, assuming their car is rotting away. Here’s the reassuring truth:…
Look at a modern car’s front wheels and you’ll see shiny metal discs behind them — brake rotors. Look at the rear wheels of many budget cars and you might see drums — closed metal cylinders doing the same job in a completely different way. Both brake systems stop your car, but they do it…
Metal is supposed to be rigid — that’s the whole point of building an engine out of it. But under the right (or rather, wrong) conditions, the metal that forms your engine block and cylinder head can slowly twist out of shape like a warped record left in the sun. It’s called warping, and it’s…
Between the simple MacPherson strut on economy cars and the classic double wishbone on race cars sits a design that quietly dominates the premium end of the market: the multi-link suspension. It’s more complex, more expensive, and more capable than either of its famous cousins — and it’s the reason many modern luxury and sport…
“How long do brake rotors last?” is one of the most common questions at any repair shop — and the answer frustrates everyone who asks, because it’s always “it depends.” Rotor lifespan varies wildly from car to car and driver to driver. The good news is that rotors give plenty of warning before they fail,…
Every car needs springs — the suspension parts that carry the vehicle’s weight and absorb bumps. But not all springs are created equal. If you’ve ever looked under a pickup truck and seen flat metal strips stacked together, that’s a leaf spring. Under most modern cars, you’ll find coil springs — big spirals of spring…
Pistons are the unsung heroes of your engine. They shoot up and down thousands of times a minute, withstand combustion pressures that would crush a soda can, and transfer all that energy to the crankshaft. And yet they weigh barely a pound. Making a piston is a fascinating combination of metallurgy, forging, and machining so…
