Replacing brake pads??

[drummerguy]

I know this is probably a stupid question that could be answered at the local parts store but....I have never changed brake pads before, my question is do I still have to bleed the brake lines if I am just changing the pads? If so, how will I know when all the air is out of the lines?

Oh yeah, I forgot, is there any difference in changing the plugs and wires on a 4.6l than any other motor? I 'm just curious because I've changed them on a 5.0, but the coil packs are why I ask.

If you are just replacing pads then no, you do not have to bleed the brakes. But, you do have to compress the caliper piston to get it back on the rotor with new pads. Then pump the brakes back up to get good pedal and you will be fine. If you have anti-lock brakes then when you go to pump the brakes up, DO NOT press the pedal to the floor. Unless you want to replace your master cylinder as well. Just lightly press the pedal untill you get good pedal. It make take 20-30 pumps. Just very short, and fast pumps on the pedal. Sometimes it is easier to do with your hand.

With changing plugs and wires on a DIS car you should just be able to pop the old ones off. It's been a while since I did a tune up on a 4.6 so I dont really remember. I work on alot of cars thrue the day. Just look at your new parts and see what you need to do. But I think the wires just pop off the coil packs just like a dist cap. Just be sure you dont cross and wires. If you dont know the fireing order then replace 1 wire at a time.

I would highly recommend getting the rotors turned at the same time as doing the pads. Just because they don't vibrate now doesn't mean they won't.

also, if it's an sn95 (I'm assuming it is because you are asking about a 4.6) you have to screw in the piston on the rear caliper, all the pressure in the world won't push it in. Have the reservoir cap OFF when you compress your calipers.

ok, I have another dumb one! When I am pumping the brakes, is the car running, shut off, in acc.? Thanks for your help!

Like said: You don't need to bleed the brakes as long as you don't open the bleeder screw. The back calipers piston needs to be screwed in cause of the ABS a tool can be bought at your local part store for $10 for this job. Doing the plugs is just as simple as a 5.0 but it is different cause of the coilpack set-up.

Just let the car run in park when you pump the brakes.
