Alright so I am replacing the calipers, rotors and wheel bearings on my '80, it seems one of the calipers is sticking.

I have my new calipers, which came with pads. The pads seem to be just loose, there's a small metal "clip" that holds them from rattling around, but it seems like they just sit inside the caliper and aren't held in place by anything (other than the rotor)? Does the metal that surrounds the pad keep it in place or am I missing pieces?



Anyone have a large picture of the caliper assembly / breakdown so I can make sure I'm not setting myself up for a brake failure here?

Also, anyone have a large breakdown of the wheel bearing / hub / rotor assembly? The Haynes manual has a small pic... and it sucks.

 

you need the clips!

 

What clips? These are supposedly "loaded" calipers, ready to install.

However, when I put the pads in place, they just fall out through the clamping area (where the rotor would be). There are two small metal clips per pad, that go on each "end" of the pads and are tight against them, but don't keep the pads from falling out, only from moving end-to-end.

 

Does this help you any?

The rotor holds them in place. If you install them in the calipers without mounting them on the rotor they will fall out. When you install the new rotors, you will need to install (tap it in with a block of wood and hammer) a bushing into the inside of the rotor. Usually they come with the new inner bearings. Outer bearings don't use a separate bushing even though they sometimes come with one.

 

85FB yes, that helped. It's the same pic from the Haynes manual but larger.

74RX4, the bushing you are talking about, you mean the wheel seal?

 

No, not the grease seal. There is a steel bushing that is pressed into the rotor. The inner bearing fits into this tapered bushing. If you compare the new rotor to the removed old one you will find that the inner bearing hole is too large and not tapered to allow the bearing to fit properly. This is because the bushing must be installed in the new rotor before the bearing.

 

FSM calls it a race. Chapter 9 pages 5-6 of the FSM describe it.

 

Yes, you will need the clips there. As stated above, they help it from moving side to side. This can also be found through Mazda as a "Brake Shim Kit". My brakes do not have the clips/shims, and every once in a while you will hear a click from the front drivers caliper.

 

Oh, yes, I know about those. They came with my bearings.

 

UPDATE:::::::

Ok so I got it done. I just gotta say...

**** you Mazda. **** whatever engineer it was that decided to require removal of the steering arm bolts to even think about getting at the lower caliper bolt. What could've taken an hour ended up taking like 6... damn crusty 30-year-old bolts.
