New Calipers And Brake Lines

[the hammer]

Man, I have used over 3 quarts of brake fluid already and I still haven't gotten clear fluid in the bleeding tubes. The new calipers are on the front of the truck, and Air is still coming out!

 

I have made sure the reservoir never ran dry, but this seems like an excessive amount of fluid for bleeding new calipers.

 

Do I need to bleed the ABS module or something?

Describe you bleeding method.

 

Left rear

Right rear

Left front

Right front

 

That is the order you should bleed by. Now what method of bleeding are you using. The most it ever takes me is a quart and I would be flushing the entire system toooo.

I think you may have the left and right sides reverse jblakeney. It should be:

 

Rear Passenger

Rear Driver

Front Passenger

Front Driver

 

in my experience you always start furthest away from the master cylinder to closest.

 

Regardless 3 quarts sounds like quite a bit

Definitely shouldn't take 3 quarts. You're sucking in air someplace. Do the calipers require bench bleeding first? I've never changed calipers so I wouldn't know.

This is part of the problem I had when I did my front calipers/hoses and master cylinder. My truck has rear drums and the bleed screws were frozen in place so I had to replace the wheel cylinders too. Changing flex hoses alone is enough to introduce a bunch of air into your system. I had that plus the rear wheel cylinders to bleed too. I could not get the bubbles completely out. I feel that as long as a guy does the 1-man bleed routine, you will always see a few bubbles go down the tubing. I think the air comes from the bleed screw threads. After wasting several quarts, I got a decent enough pedal to drive it and took it to the dealer for a quick bleed and rear brake adjustment. For $50, I have a better pedal than I had when it was new.

 

Look on the bright side, you'll have all new fluid, flex hoses and front brakes.

I was bleeding in the correct order, it is just nuts as to how much little air bubbles are in it. I will go to the dealer soon and have them do a flush with whatever tools they have cause I am really tired. hahaha

A cheap Motive power bleeder helps quite a bit easier IMO. Makes it a 1 man job and can push serious amounts of brake fluid through the system. I've never used more than 2 quarts even with flex line or caliper replacement. You should be able to get to ZERO bubbles. Brake fluid is reasonably cheap. better to use more and get all the bubbles out.

 

Regarding the abs circuit, so long as you did not suck air into the master cylinder and pulled it to the abs circuit, you should not have to worry about the abs when bleeding. Sometimes they will leak though. The right way to purge the abs is to open the circuit with a tech II and bleed. The poor mans method is to completely bleed your brakes as best you can. Drive on a dirt/gravel/icy surface and hammer the brakes to kick in the abs for a few seconds. Bleed and repeat again if necessary. I've used this method myself and it seems to work.

+1 on the Motive Bleeder. That this is sweet. I flushed my brakes on my 02 Silverado and it only took on liter. Reason I said liter is because I used Super Blue and it comes in liters.
