Thanks for joining me for the latest installment of the Auto Specialist. Last time, we helped a reader named Jonathan figure out why his Honda Element wouldn’t start (it turned out to be a faulty ignition switch). We also answered Elaine’s question regarding how often she should change her car’s air filter.


Question: I own a 1998 Mazda Protege with 150,000 miles on it. I bought it used several years ago and it has behaved surprisingly well (I keep it well-maintained). I’m writing because my front passenger-side brake is leaking fluid and it’s not working as well as it should. What are my options (the lower the cost, the better)? I haven’t gone to the repair shop yet.

Answer: I appreciate your email, Louis. Your options depend on the nature of the leak. Here’s what I suggest: remove the front passenger tire and take a look at the brake to find the leak’s source. Look closely at the pads. If they’re wet with fluid, you’ll need to replace them. Unless there’s another reason your brakes are not working properly, plugging the leak and having the pads replaced (if necessary) should resolve the problem. By the way, I would also bleed the air while you’re at it.

That’s it for this installment. I’d like to thank Jack and Louis again for their questions. Jack’s question, in particular, strikes a chord with me. I’ve seen countless instances in which people buy used or rebuilt auto parts that fail long before they should. For the important components, like alternators, catalytic converters, and anti-lock brakes, buy OEM replacements. In my opinion, it’s better to spend a few extra dollars for the peace of mind. Until next time, drive safely.
