i am ready to put on new brake lines and hoses from the master cylinder to the rear and across the rear of the car. is there a specific order to bleed the brakes?

Right rear outside
Right rear inside
Left rear outside
Left rear inside
and while you are at it
Right front
Left front

Just remember to start furthest from the master cylinder.

Check out the brake bleeding and diagnostic procedure in the Tech Tips located on the red tabs at the top of this page.

I was always told that you bleed furthest from the MC first also, however, if anyone believes what is published in the Haynes manual the order is:

LR, RR, LF, RF (if only one bleeder per caliper)

LRi, LRo, RRi, RRo, LF, RF (for inner and outer rear bleeers).

The second set was the order I used on mine and it seemed to work great.

Before you remove the long line that runs from the front to the back of the car along the drivers side frame, you may want to think twice. It is said by some wise men that this line can only be replaced with the frame off- or have you already done so?

Been a while, since in bleed the brakes on my C3, but believe that you can't gravity bleed the back. So, you need a helper. There are two bleeder fittings for the rear. Think you must leave both fittings open. Also, once the fluid is coming out air bubble free, I usually tap the caliper with a rubber hammer, while the helper is stepping on the pedal, to make sure of no trapped air.

So, uh, forgive yet another stupid question, but......

....if the front hydraulic system is seperate from the back, why do we always start with the back?

Can I do left-front, then right-front? Then do the rears later?

After all, if it helps to have the front of the car lower when bleeding the rears, then let's get the fronts out of the way first, right?

well i hope i haven't made a mistake but there was a hole in the line about half way back so i really had no other choice but remove the existing line. i guess i'll try it and see if i can install the line or not. if not they what alternatives do i have short of taking the body off the car? i'm not sure i'm ready for that. my car is but i'm not....

Maybe you should ask the question about the front to back line in a seperate thread before you try to install it. I have read some people say they have done it and others say it is impossible. I am sure where there is a will there is a way. Don't panic yet. :nono:

I did not bust but sort or crushed one. Ran a new line but bent as I went and used brake clips screwed into the frame. The other post on the in line repair makes more sense.
