Piston Slap: Deep-Sixing Unknown Friction Materials?

Hi, Sajeev! I’m a long-ago occasional TTAC contributor, occasional B&B pontificator, and longtime admirer of your column, with a question of my own.

My brother just picked up a very used ’09 Mazda6 Grand Touring V6. Lotsa horses, in need of brake service to rein them in. He’s hearing and feeling a pulsing through his brake pedal, sort of a low rhythmic moaning tone. It could be wear indicators, but more likely it’s a warped front rotor. Either way, he’s pretty confident he’s going to have to replace all the friction materials, including the rotors.

Which leads to my question: What’s a not-crappy brand of brake parts? He doesn’t want to expend all the labor on replacement, only to have them immediately warp again the first time he heats them up (which he will – especially with 274 ponies, he’s an, er, enthusiastic driver). Everybody knows Brembo, but who else sells quality?

Sajeev, what ever happened to 14-inch wheels? I mean, seriously, does the Caliber really need to be shod with 17-inchers? Why does my dad’s new half-ton pickup have 17-inch wheels? His old one had what used to be the industry standard 235-75R15. He about had a coronary when he found out new tires would be over $100 each. Perhaps if I put on my tinfoil hat, I’d say the tire companies are behind this. So really, does the average family sedan or minivan really need anything bigger that a 15-inch wheel/tire?

  • EBFlex What a colossal waste of money. But this installed administration has yet to spend one cent on something that is actually useful and actually leads to some progress. But apparently this is just what we need….a bunch of extremely overpriced but short ranged busses. It’s amazing that all our problems are solved that they have time to waste money on these little pet projects.
