Bleeding Brakes

[Juan4DCB7]

So I am going to bleed my brakes someday next week, I just wanted to know what is better DOT 3 or Dot 4?

I also don't know if i should bleed the brakes staring from the farthest wheel from the the master cylinder and working my way there,

or doing it the manual way which says
"1990-95 Accord: Right rear, left front, left rear, right front"?

If I remember correctly, you can only use DOT3 brake fluid. DOT4 will damage the seals in your master cylinder and calipers.

read the cap on your master cylender it says either dot 3 or dot 4.. and as for the bleeding go passanger rear, drivers side rear, passanger front , drivers side front, good luck cheers!

There are 2 brake channels/lines, right rear to left front, and left rear to right front. They are diagonal channels and it is set up that way so if you get a failure at one of the soft brake lines or one of the cylinders, or if one hard line fails, it will only affect one channel and you will still have half of your brake system.

Supposedly, and I've seen no convincing logical explanation of this so far, supposedly you need to bleed the rear line of each channel first before doing the front line of the same channel. That's the important principle to remember. Whether you bleed both rears first before doing the fronts, or go right rear left front, left rear right front, it makes no difference. They both accomplish the same thing of bleeding the rear line of the given channel first before doing the front line. Which is supposedly important.

Assuming the importance of doing the rears first as a fact, the reason for differing instructions on this is that sometimes manuals give one procedure out of several possible because that's easier than explaining all the principles and considerations around the procedure. And other times they give one procedure because that's the only way to do it. Without really understanding all aspects, it's hard to tell which is which sometimes when reading instructions. In this case, doing both rears first seems sequentially similar or identical (depending on how you are looking at it) to doing one rear and then the corresponding front, then the other rear and its corresponding front.

thanks guys, all I need to do now is buy the oil and a bleeder hose.

You can do the job easily by yourself with just some hose ( i believe a 2 foot lenght of 3/16 or 1/8 inch internal diameter works, for under a dollar, or just buy $8 one man bleeder set at the car shop) and a 2 foot long or so piece of 2x4 or something else to jam between the brake pedal and the driver's seat for when you have to go and tighten the bleeder screws again or get out of the car to add more brake fluid.

Put the wood against the driver's seat and the brake pedal, then slide the driver's seat forward until the brake pedal bottoms out. Now you can go outside the car and do whatever and you are guaranteed not to have sucked any fluid or air back into the lines.

If you have a 2 foot long breaker bar that works too. but it's kind of pointy pressing on the car seat and doesn't stick to the brake pedal as easily as the end of a 2x4 so it's trickier to use.
