1998 Ford taurus se, Today when i check the brakes, I found the right rear brake has problem, the outer dust seal of the piston broke, It has a about 3mm long gap. And the brake pad has a crack. Now the brake work well, What shou i do? keep it or replace the seal. How about the pad, the thickness of the pad is about 7mm, but it has a crack?

i would replace the seal. Go to your autoparts store and they sell rebuild kits that include a rubber boot. Im assuming these are drum brakes.

As for the pad, i personally would not worry, but others would say replace it.

A set of breake pads for both sides is about 18$ so just do the whole back end, not just one side.

your getting raped on the pads...i just got some from a local store for 20$ for disk brakes!

As for rebuilding the rear callipers...its fairly easy...

take the calliper off the car....pump the brake till the piston falls out.

Pull out the old seal, place the new one in the grove, strech the seal around the piston that poped out and press the piston back in as far as possible (will not be far)

Then take the ford tool or a set of needle nose and use them to screw the piston back into the assembly.

Once you have it apart it will make alot more sense. and yes, you have to SCREW it back in as there is a parking brake assembly inside

My 'Haynes repair manual' told me how to rebuild the front caliper, an it told me it difficult to rebuild the rear caliper, need special tools, the tools is expensive, it's better to buy a new caliper. But your method is the same as rebuild the front caliper, only the pressing the piston back is different. And this afternoon i screwed the crack rear piston 180degree with a plier, so If follow you, i think i can rebuild the rear caliper.

No need to take off the hose?
As i Pull out the old seal, will the brake fluid leak? so i should bleed the four brake?

And, can i 'pump the brake till the piston falls out'? Will it hurt something? My 'Haynes repair manual' told me using low pressure air, what's that?


Thanks!

Or you mean, if i just replace the dust seal, and keep the rubber seal. It's easy, and no need to bleed brake fluid, no need to take off the hose, and just depress the brake pedal to pump out the piston?
