what about this
http://www.ehow.com/video_2327156_co...-calipers.html[/quote]

That really only works with the front calipers, and even then, even if you could get the screwdriver in there, chances are you'd bend/break the screwdriver.

I've regularly swapped pads on many different cars and I've never used that trick--it wouldn't move the pistons in enough in any case. I've also never used a brake "special tool"--careful use of C-clamps, channel-lock pliers, etc. whatever's appropriate has always worked just fine.

For example on my Evo I can just open the bleed screw, connect the bleed bottle and compress the pistons with my hand. But it's a very different caliper design. The Evo has separate parking brake drums so the rear pistons can be compressed just like the front. Most cars (those that have rear disc brakes) have rear parking brake adjusters that you need to turn to compress the rear pistons.

Man, you weren't kidding when you said you have to push ungodly. It's two days later and my hands still hurt but I was able to get the caliper back in and get the brakes installed.

Thanks for the help! Next time around it will be much easier now that I know what to do

Next time spend the ~$20 and get the caliper compression tool....... makes the piston go in "like buttuh", plus then you'll have the tool for the next time around. Some auto parts stores will loan them out for free too.

Happy to help.
[/quote] we're talking about a c-clamp right?
[/quote]
NO dont go with a c clamp, you will likely cause damage trying to jam it back it... you have to put pressure and turn at the same time, the compression tools that you can rent/buy do this
[/quote]

i've always used a c-clamp and never had a problem

Re: How-to Guide: Rotor, Brake Pad, and BrakeLine install/replacement (FRONT / REAR)

Hi all, I'm about to have my brakes done over the upcoming weekend. I bookmarked the how-to that was reposted on wildweasel with the torque settings. Can anyone tell me where these torque settings came from? Are they reliable or did someone just guestimate?

Thanks!

Re: How-to Guide: Rotor, Brake Pad, and BrakeLine install/replacement (FRONT / R

Melissa, chances are the torque specs are from the Mazda factory service manual.

Here's what I got out of my copy of the FSM:

Front brakes:
Caliper bracket bolts: 78.5-102 N-m (57.9-75.2 lb-ft)
Caliper slider pins: 25-30 N-m (19-22 lb-ft)
Brake line fitting: 20-27 N-m (14.8-19.9 lb-ft)
Brake bleed valve: 7-9 N-m (70-79 lb-in) (regular 3), 12-16 N-m (107-141 lb-in) (Speed 3)

Rear brakes:
Caliper bracket bolts: 59.5-76 N-m (43.9-56.0 lb-ft)
Caliper slider pins: 25-30 N-m (19-22 lb-ft)
Brake line fitting: 19.1-23 N-m (14.1-16.9 lb-ft)
Brake bleed valve: 12-16 N-m (107-141 lb-in)
