im replacing both my front and rear rotors and pads but i forgot my repair manual at my apartment, and i was wondering if i have to done anything special and what the bleeding procedure is for a manual bleed.

MAN! I am still never able to get on the site at the right time. Every time I go the 82 280zx is not available. I have to set an alarm every hour to check that site...

Do you even need to bleed them? Shouldn't have to.

But, Start with the brake furthest away from the MC, and work your way to the next furthest. Bleeding brakes, is bleeding brakes. Not rocket surgery.

what is the advantage of bleeding brakes...I am in process of replacing the front rotors and pads on my 82 ZXT... All I did in addition was to re-grease the barrings (just to be safe) and rest is just change. I did not bleed the brakes, was it a mistake on my part?

scorpionp54

ok thanks guys, but do you have to do anything to the rotors or do they just come off

njgheewala

After you have the rotor removed be care full not to drop the barrings...You would have to separate them from the part where the wheels go (sorry cannot remember the technical term for that part).

Here is another site you want to go to get online service manual.

You do not have to take the rotors off unless you are getting them turned.
If you want to, you will remove the dust cap, remove the cotter pin, and the crown nut. remove the wheel bearing washer,a nd outer wheel bearing, then the hub will come off with the rotor.
I would suggest cleaning the wheel bearings with some good brake clean or other solvent, and packing them with good new grease while you are there. Outer and inner. Might as well while you are there.

The point to bleeding brakes is to get all the air out of the hydraulic system. If there is air in the system, the air will compress where the fluid will not and will make for spongy feeling brakes.

you have to bleed the brakes to get air out. air gets in by one of your components going bad, or the line being disconnected somewhere. so, if you take a line off to replace a caliper or something, or replace the master cylinder, you have to bleed after to get new fluid in. if your master cylinder leaks a little bit, you have to bleed frequently to get the air out, cause if fluid is going out, air usually goes in.

Also.
Brake fluid is hydrostatic. Meaning it will absorb water. Over time your fluid will go from clear to milky, or even into a sludge if not changed. You can always change the fluid by bleeding and filling at the same time until it's flushed.

Thanks both !
But there is no reason to bleed brakes if you have not taken the caliper out and only replacing the rotors and pads?

njgheewala

Thanks...that answers my previous question

Ratfink

If you are not disconnecting the brake lines, or they are not already leaking, there is no reason. You can replace all the pads and shoes without taking lines off.
