Started noticing the car drifts slightly to the left whenever I brake firmly from speed. Not a huge pull but enough that I'm correcting with the wheel. Tyres are new and alignment was done recently so I'm thinking it's brake related, maybe a caliper sticking on one side. Before I start guessing I wanted to read up properly, so I went to click here for a breakdown of brake wear issues and it did mention uneven braking as a warning. Now I'm wondering how urgent this is, can I keep driving gently for a week or two or should I get it looked at immediately? Also anyone know if a sticking caliper is usually a cheap fix or does it tend to spiral into replacing half the braking system?
