Piston Slap: Deep-Sixing Unknown Friction Materials?

TTAC Commentator tonycd writes:

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?

Piston Slap: Design Weak: Big Ass Wheels

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?

  • Analoggrotto Does anyone seriously listen to this?
  • Thomas Same here....but keep in mind that EVs are already much more efficient than ICE vehicles. They need to catch up in all the other areas you mentioned.
  • Analoggrotto It's great to see TTAC kicking up the best for their #1 corporate sponsor. Keep up the good work guys.
  • John66ny Title about self driving cars, linked podcast about headlight restoration. Some relationship?
  • Jeff JMII--If I did not get my Maverick my next choice was a Santa Cruz. They are different but then they are both compact pickups the only real compact pickups on the market. I am glad to hear that the Santa Cruz will have knobs and buttons on it for 2025 it would be good if they offered a hybrid as well. When I looked at both trucks it was less about brand loyalty and more about price, size, and features. I have owned 2 gm made trucks in the past and liked both but gm does not make a true compact truck and neither does Ram, Toyota, or Nissan. The Maverick was the only Ford product that I wanted. If I wanted a larger truck I would have kept either my 99 S-10 extended cab with a 2.2 I-4 5 speed or my 08 Isuzu I-370 4 x 4 with the 3.7 I-5, tow package, heated leather seats, and other niceties and it road like a luxury vehicle. I believe the demand is there for other manufacturers to make compact pickups. The proposed hybrid Toyota Stout would be a great truck. Subaru has experience making small trucks and they could make a very competitive compact truck and Subaru has a great all wheel drive system. Chevy has a great compact pickup offered in South America called the Montana which gm could make in North America and offered in the US and Canada. Ram has a great little compact truck offered in South America as well. Compact trucks are a great vehicle for those who want an open bed for hauling but what a smaller more affordable efficient practical vehicle.
