Brakes Squeak After Being Serviced

Numerous times, I've been asked why their brakes squeak and/or pulsate after doing their own brakes or having their brakes done by a non-dealer.

I'd like to start by saying that I have very strong opinions on this.  I was taught how to brake jobs by a childhood friend who was a certified Ford front end mechanic.  I've followed his advice and it has never let me down.

Ok.  In regards to squeaking, it is caused primarily by either a warped rotor/drum and/or dirty hardware.

Here's what I do, which has paid off for me:

• Purchase quality pads/shoes
• If you need to replace a rotor or drum, replace both on the same axle.
• If your rotors and drums can be resurfaced, always have them resurfaced.  You can have this done at places like NAPA and Kragen for around $15-$35 each.
• Always replace the hardware.   What I mean by hardware are the springs, clips, and metal inserts that make up the braking system.  Check out the following images to get what I mean.
• Disc Brake Hardware:  
• Drum Brake Hardware:   
• If your car requires you to pull the wheel bearing to access the rotors, replace with new bearings.
• Lastly, always perform a full brake system flush.

I have had more debates on this than I care to recall.  But, all I know is that following these simple rules, I have avoided many do-it-again jobs.  In addition, many people have not taken my advice, and I end up at their house in a couple months trying to figure out what they did wrong.
