Need tips on replacing front rotors

Wife has an 07 mazda 3 that is in need of new front rotors (steering wheel shakes bad when hitting breaks). I want to give it a shot and looking for some tips.

I'll replace the pads also.

Do I need to drain the brake fluid before or after removing old rotors? Is it a fairly easy job to do? I replaced the struts a few years ago and this seems a little easier than that. Anyone know the correct size tools I'll need? Will I need an alignment afterwords?

Did this shaking start suddenly or has it been gradually getting worse? Unless they're badly warped or cracked, rotors shouldn't cause the steering wheel to shake 'badly'. Sounds more like a worn out LCA bushing or a ball joint. Not saying it doesn't need brake work, only that there's probably some other repair needed as well.

If its your First Time doing a Front Brake Job...

Do your RESEARCH...Watch DIY videos on YouTube....

Make sure you have the right tools....And you know what your doing....Also after doing brakes its IMPORTANT to do a proper "Bedding of Brakes"

  1. Actually, I think, it doesn't matter if you bleed brakes first or last. As lond as you don't push dirty caliper fluid back into line, you will be fine. But it will be more efficient to remove dirty fluid before by opening valve and pushing caliper in (operation you can't avoid). And after installation flush your lines.
  2. Very easy. In Mazda, most complex is to separate roror and spindle.
  3. No, no alignment needed after brake jobs
Here, I just posted some highlights of my yesterday brake job,

Thank you guys for the replies. I was not able to log in for some reason but now it's working.

The steering wheel and brake pedal has been shaking while applying the brakes for a good year now. It has recently gotten worse and worse though. Now when I'm close to a stop the car will rock back and forth as I'd the brakes are slipping at certain points or something. I only drive the car about twice a week. I drive to work on Tuesday morning and then drive it home Friday after noon.

Are the rotors and pads different on the sport and other models? Mine is not a sport and has the smallest engine. I'm not sure what model it is really (wife's car that she bought when I first met her). I'm thinking I will just change front and back rotors/pads since it probably needs it anyway.

I have watched a few videos and it looks like I need a special tool for the rear pistons? They have to be turned and rotated at the same time I guess? Can I just use a regular c-clamp for the front pistons?

The 2 things that are most intimidating to me are bleeding the brake fluid and compressing the pistons. The videos are nice but often times they tell you what to do and stop recording and return after its been completed. I'd love to have step by step with pictures or even a video if possible that shows all the steps. One video I watched the guy put lubricant everywhere it seemed. To me lubricant and brakes just don't go together but I'm no mechanic.

Is it safe to use the wheel key with a impact gun? I'm tempted to just replace them with regular lugs just because it's a pain to find that key when I need it most of the time!

Put the key in your console storage box.

Don't use a lock and key style lugnut, and you don't have to worry about it.

Was kind of funny / sad seeing one break at a tire shop I was at the other day.

Isn't exactly one of those things you can get anything done when that happens.
Especially in case of emergency.
