good video like your safety approach, and assistant mechanic. Also thanks for giving the torques needed to do the job

Thank you.

Bless you! provided torque ratings!

Hi, I tried doing this job whiteout looking at a video, but my caliper doesn't want to retract. Would you or anyone know what to do ?

[@brentworksgarage]

Check out 4:38 of the video. You'll want to Turn the piston back in, DO NOT push it back. The rears must be turned back in. Make sure your parking brake is off prior. Could try opening the brake bleeder then turn the piston back into the caliper. Note that you may need to bleed the brakes after this. Also make sure the indents/grooves on the brake piston are at the 12 and 6 o'clock position. Image at 4:38. Good luck.

@@brentworksgarage wo.. I'm pretty sure every other videos about changing rotor and/or callipers on mazda 3 2017-2018 insists on NOT turning the piston.. It must be push in

[@brentworksgarage]

​@@patricegamache2114 That would be for the cars equipped with the Electronic Parking Brake. You are correct for those EPB calipers, they need to be pushed back. They also need to be placed in maintenance mode prior to pushing the piston back. The mechanical park brake (hand brake) models need to be turned. Thanks for your comment... I wasn't aware this generation had the Electronic Park Brake. -The EPB appears to have been added as an option in the 2017 model year.

After I replaced the rear brake pads on my Mazda 3, the handbrake does not work, did I do something wrong? :(

[@brentworksgarage]

Was it for sure working prior to replacing the pads? There was a recall (#1217F) for the park brake. I am in a similar situation where my pass. side doesn't work. Will have a video showing how to replace caliper in the future (hopefully). You didn't disconnect the park brake cable from the caliper while replacing the pads did you? What was your method of getting the piston back into the caliper? Rear calipers need to be turned back into the caliper (if electronic park brake then pushing in only, no turning). Both sides are not working with park brake?

[@uchabidzinashvili6927]

@@brentworksgarage Thanks for the reply, it was working fine before the change, park brake cable is still working, I put the piston back in the caliper by pressing it (it isn't electronic), I didn't understand what should be turned?

[@brentworksgarage]

@@uchabidzinashvili6927 Oh I see. At the 4:40 mark of the video I put text that the piston should be turned back. If it was really tough to push back you might have broken the parking brake mechanism. Is your car an automatic or manual transmission? Not that it makes much of a difference now. Could take it to the local shop and get their opinion on it. Check the wrecking yards for your year of Mazda to get a replacement caliper (or buy new). Make sure to search for the correct country of origin as brake parts differ from Japan and Mexico.

[@uchabidzinashvili6927]

@@brentworksgarage Do you think the caliper is damaged? I don't want to have to buy a new one but it's an automatic and I really need a handbrake, it's made in Mexico and I hope I can get it, thank you very much

[@brentworksgarage]

@@uchabidzinashvili6927 The brakes should work fine for normal driving operation, but I think you may have broken the internals for the parking brake. I think that is what someone did to my brakes on one side (other side still holds the car). Luckily you have an auto transmission so the transmission will hold the car, but it would be nice to have all parts working as they should. Check RockAuto.com or local wrecking yards for a replacement. In your case Mexican made Mazda3. I am not sure if there is a rebuild kit for the parking brake assembly. Good luck.
