Our first MDX just turned over 800 hrs. and I'm going over the 800 service interval .
Not to hard to check them . You can see how much pad is left by looking through the openings in the caliper .
If you have the anti chatter clip you can pull it out and look also .
Caught ours just in time .
Anything less than 1/32 " of an inch of pad material needs replacing .
First remove the cap on the brake reservoir .
The 2 wire clips just pull out . There are 2 bolts on backside that removes the caliper . The brake line can be pulled through the rubber grommet a little to make it easier to work on .
I've seen the same type of brakes on small cars .
The pads come as a kit to do one wheel . In the package includes new wire clips and instructions . The instructions mention to use a screw driver to pry on the old brake pad ( while its on the disc before removal) to push the piston back .
There is no through opening to use a clamp the normal way . I had to improvise a bit and used one of the wheel nuts to push on the center of the piston so it doesn't bind sideways .
Watch the piston and feel how it goes back in . It should be easily pushed back not jumpy or excessive force with the clamp . Push it till it just bottoms out .
Pads only go one way with friction material facing the disc . The slots sit on the wire pins .
Assemble disc pads and pins in caliper . also de-glaze the disc and check to see if it's warped or excessive wear . The pads ALWAYS wears more on the piston side since it 's the pad that makes contact first .
You can slide the anti chatter clip in if yours has it .
You can now install the bolts and torque them to 35 - 40 ft. lbs.
While your here you can clean up the bleeder screws threads and put some ant seize on them .
That way if the brakes had to bled later on you might have a better chance to get them to break free with out snapping one off.
Picture above of De-glazed disc with some medium grit sand paper . Before you test drive ....push the brake pedal down a few times first to get the new pads out to the disc .
I'm a bit of a pack rat so I'll keep the 2 outside old pads and a couple of wire clips ( for just in case ) . Most likely will never use them but you never know in this business . I've seen parts missing that leaves you scratching your head at times .
