The drum brakes on the inside are the emergency brake. When you set the
emergency brake those shoes are pushed out against inside of the rear disk
rotor that acts like a disk drum. Sometimes these are adjusted too tight
and the rotor won’t come off. There is an adjustment to loosen them if that
is the case. If the rotor hangs up on the pads don’t force it off or you
will damage the emergency brake pads.
Its called a drum and hat system. The drum is a cable driven parking brake
that is separate from the hydraulic braking system and the had is the disk
/ pad brakes that are connected to the hydraulic system.
What you are seeing is the parking/emergency brake. The rotors on this
system are a disk/drum combo, where the internal shoes are only used when
the parking/emergency brake is engaged. Occasionally you will need to back
off the parking brake using the adjuster the same way you would on a set of
drum brakes. I’ve done several of these and only had to deal with the
adjuster twice.
I’ve never had to do that, and I’ve always been able to just retract the
piston. I guess you’re concerned about creating pressure back in the
cylinder and breaking something? From what I’ve read and experienced, the
pressure isn’t high enough to create a problem. Thanks for the question.
Don’t ever set your tires at the pressure on the tires. Go off the
manufacturer’s settings. It is posted inside the driver’s door or the fuel
door. It’s also in the owner’s manual.
Did this today on my 2007. Need a T-47 Torx for your rachet ($3.50 at any
auto supply shop) to get the caliper pins out – don’t recommend a drill
bit. Disks needed some Liqiuid Wrench and 10 minutes to disolve the rust
before they would budge for the hammer. About an hour for the first side
and 30 minutes for the other. Not too tough to do. Thanks for the video.
On the rotor, I had to hammer it off and found that constant wheel rotation
was the trick. I had my son hammer while I slow spun the hub and it cracked
open pretty quick. We also applied penetrating oil.
Thanks for the comment, and glad you liked it.I used an Allen bit, which I
also use on my Grand Caravan. Interesting that you used a Torx, but the
service manual definitely calls for an Allen bit. Maybe you were just able
to jam it in and it was able to catch the sides of the hole? But if it
worked for you, great, there’s lots of techniques.

Whats the name of the tool used to loosen the brakes?

but when you took the disks off, underneath looked like drum-disk-pads, but
I think my eyes deceived me…..
Hi. Definitely disk brakes!
Definitely disk brakes!

it looks like drum brakes inside of disk brakes. Are my eyes deceiving me?
thanks for posting.
Yes, thanks for posting that. Good point.

Hey Doug do you remove the brake fluid cap before you retract the piston or
is it okay to just retract the piston?
great vid did mine today, totally used this vid saved $100 at the shop.
Thanks
