Updates on the brake situation: https://www.clubcivic.com/forum/threads/brakes-pulse-shaking-the-steering-wheel-and-car.233780/post-3462653
Mothership is at the shop today. The parking brake has been sticking when I disengage it in the morning, and between that and the brakes pulsing I finally decided to throw money at the problem since I don’t have the free time to work on it. It should have waited until next week, since I’m driving to Atlanta after work, but oh well.
The shop called and said that the rear brakes are a total loss, and they’ll replace all of the hardware for $400 Apparently one side’s wheel cylinder failed, and the other side was over-heated as a result.
