Q: Brake booster heat issue.
So I'm having issues with the brakes having a slight drag with heat. Master is a new German replacement. (Second time it's replaced to verify good) booster is new aftermarket. VW added a brake booster heat shield in years after mine and I'm wondering what a brake booster would do if it's getting hot from exhaust and turbo heat. It's not extremely close but my injectors are very worn so I suspect my egt is higher than normal due to overfueling. Pulling the pedal up (unnoticeable amount) causes them to release smooth as glass but it happens again soon. Any ideas would be great. It's all 4 brakes dragging, new soft lines all around, new calipers too.
My car has 255000 miles.
