How to Collapse 2006 Mazda 3 brake caliper
 

Its Easy really considering everyone on this website and others are stupid and cant tell you the right thing to do. Ok first thing 2 do is remove the brake caliper from the mount you don't have to take off E-brake cable or Brake line you can just let it dangle now here`s the tricky part your ether gona need a spanner wrench or the spanner bit for a impact wrench there specialty tools I used a adjustable spanner wrench so I got lucky and didnt have to go find one now here comes the hard part lossen the brake bleeder valve its under a small rubber cap located on the rear of the brake caliper so that the fluid can come out of the brake caliper then use the spanner tool you have on the caliper press itself. turn it clockwise you know righty tighty lefty lossey untill caliper press is flush with caliper press rubber grommet is should be enough room for new brake pads and a rotor if ya turned it in enough and thats it you`ll have to bleed the brake lines but you should do that every once in awhile anyway well good luck and id like to thank all the idiots that didnt help me so i had to fiqure it out myself https://www.mazda3club.com/images/sm...ileyshot22.gif

actually there was no need to pend the bleeder valve.... any local auto parts store rents out caliper compression tools that have a bit that fits into the little dimples on the piston and applies pressure to compress and turn at the same time, so again there is no need to open the bleeder and then have to bleed the brakes later... hell you could have actually done it with needle nose plyers and just push on the piston while turning... thats the key, push and spin at the same time otherwise its going nowhere

Just because one or some people may have given bad or incorrect advice, it doesn't make all of us that way.

Ok ok um yeah your right most people here might not be stupid

+1. I suggest renting or buying a brake caliper compression tool. I got one from Harbor Freight for $18. It sits into the dimples on the piston head and locks inside the caliper, then you just turn. You can do the same thing with pliers, however the caliper tool is much much easier. With the tool it was basically five minutes per piston to replace the pads.

Thanks to icspots!
 

Man, you just saved me a hoard of money and a lot of aggrevation with the Harbor Freight caliper piston tool post. Many thanks!!! :-)

I just finished replacing the rear pads on my '06 and although I got the pistons in fine, I opened the bleed screws while doing it and although I tried to be careful after everything was reassembled I tried to bleed the brakes to make sure there was no air but I was surprised to find that no fluid was coming out. Do you guys have any idea why this may be?

try pumpin then bleeding the brakes and it that doesnt work then turn the key on engine off and try pumpin it and bleening it that way. some cars have electronic crap that wont work unless the key is on.

It doesn't help you at this point, but you don't have to open the bleeder valve to change the pads.

on the rear piston there are 2 holes. take a needle nose pliers and stick it in the holes. while turning the piston clockwise apply pressure. the piston will collapse. i have a mazda 5 and just replaced the rear brakes. i had to use long needle nose pliers to get enough leverage. its pretty tough to do but it works. you can rent or buy a special compressor tool but its cheaper using a little elbow grease ya know. please do not listen to that idiote that said to loosen the bleeder valve. he has some nerve calling other people stupid when he does not even know what he is talking about. and you do not have to bleed your brakes once in a while either, thats just stupid.
