Bleeding Brake Lines?

[70-Chevy]

What order do I go in to bleed the brake lines? Isnt it the furthest from the master cylinder all the way towards the closest? Any other tips or tricks to get the job done better is welcome, Thanks guys.

Everything I have read, says right rear, left rear, right front, left front.
Check www.classicperform.com for more information on brake bleeding, and I think brothers had information on their website also. Check the classic truck mags. websites also.

While I will get flamed for saying this... that is way outdated info that doesn't matter anymore.

That rule was made when there was one line coming from the master cylinder...one resivour... back in the old days... older than our trucks.

Now (and including these rigs) they have basicly 2 systems in one. The rear brakes and the circuit that feeds it... is all seperate from the front stuff. So if you bleed the front first, the rear is totally unaware of what's going on... and unefected.

Everything you read will tell you to do it the way they did it 50 years ago, and some people will stress over it and call you anidiot for not doing it that way.... but it simply doesn't matter anymore.


Here's another one... go ahead and set your battery on the cement floor. it won't go dead.

You'll be called an idiot for doing it, but it won't go dead.

You are right about the 2 different systems, my dad drove a 65 gmc around for years with only front brakes in the mid 80's, and that was with the single reservoir m/c.

Speed Bleeders. SO worth the $$.

You can find them in the HELP! section of the auto parts store. I have them on my front brakes now, looking to do them on the rear really soon, as well as a full set of them for my Frontier.

Plenty of cars even use a diagonal system where the front right side linked to left rear and vice versa.

I'll get flamed for this, but I bleed most all my brakes by gravity. I have for years too. I don't like the pump and squirt stuff and don't have a pressure bleeder.

I work alone, so I simply fill the reservoir and lay under the truck contemplating the meaning of life while the fluid makes it's way down and out the bleeder screw. Then, close it and go to the next wheel. It helps to tap lightly on the metal lines with your bleeder wrench while you're waiting. That tends to break up bubbles and make the fluid flow quicker.

Do all 4 wheels, then pump the pedal a few times vigorously, then repeat the bleeding procedure. Works every time, and doesn't usually take over 10 minutes or so.

Tx.... No flaming here... I do it the same way personally.
Pumping the pedal to pressurize the fluid stirs it all up and causes large bubbles to become millions of small bubbles.

I am in total agreement with Longhorn Man. I believe starting with 1968, vehicles were required by law to have separate systems between the rear and the front, hence two reservoirs. When I'm bleeding brakes by myself I attach a hose snuggly to a bleeder and drop the other end of the hose into the bottom of a container (usually an empty beer bottle, just happen to have one laying around ) then open the bleeder and while keeping the master full I gently operate the brake pedal down and up several times keeping the end of the hose at the bottom of the container under fluid, then snug up the bleeder and move on to the next wheel.

A made a power brake bleeder for about $10 that sure works great - especially for people like me who usually work alone link to power bleeder
