Piston Slap: The Self-Lathing CRX?

Gareth writes:

Good afternoon Sajeev,

Read your latest and I’m determined to help you out. I recently had a bone-stock 87 CRX Si follow me home from an impound auction and, if I can get the damn thing through an Ontario Safety Inspection, I’ll let TTAC’s very own Derek K drive it.

Therein lies the rub, or brake rub really. The front discs were rubbing, a lot. Constant grinding sound as the wheels turn. I have since removed/lubricated the caliper sliders (they were a bit stuck from sitting) and measured the discs and pads using a measuring tape and straight edge, everything is above min specs.

With the pin lube the grinding noise has abated somewhat but continues, worst is passenger side.

The discs don’t feel warped (no front shudder under hard braking).

Your thoughts?

  • Jkross22 Their bet to just buy an existing platform from GM rather than build it from the ground up seems like a smart move. Building an infrastructure for EVs at this point doesn't seem like a wise choice. Perhaps they'll slow walk the development hoping that the tides change over the next 5 years. They'll probably need a longer time horizon than that.
