changing suspension,brake bleeding question

[79elcamino]

my front suspension are a connector for the brake lines on it and the piece where the two brake lines connect to part part of the suspension and not just bolted on so i assume the new suspension will have the same piece, my question is if i disconnect the brake lines from the connector and connect them on the new strut will i have to bleed the brakes or can i just add brake fluid to replace what came out??

Anytime you disconnect a brake line or hose you should bleed the system. Even a very small amount of air in the lines will cause problems.

If you are just disconnectiong the brake line from the bracket that holds them in place to the strut you will not need to do anything as you are not opening the brake lines. However if you remove the line from the caliper and (and see fluid coming out) then you need to bleed the brakes.

And if you have never bleed brakes you always start at the brake farthest from the master cylinder and progress accordingly.

I just replied to your newer post on this subject- and it occurred to me that your problem may simply still be that you have air in the lines, that they haven't been bled enough from the initial changes you made..

I have just replied to your newer post.
I will probably agree, you may need to bleed them more thoroughly.
Have you changed the suspension so that the carbsits lower?
Does your vehicle have a brake bias valve on the rear axle, this will help balance braking when the vehicle senses weight in the rear.
This valve may be closed when you have the vehicle on the ground and you bleed the system.
As you're then driving round, the travel of the vehicle heights allows the valve to open and close, thus allowing the air trapped in the system travel around. Which in turn could possibly cause your issue.

Another possibility, when you have changed to a different suspension and height, as you lower the vehicle back down, are your flex pipes (the rubber pimps) being trapped or crimped in any way?

didnt change ride height, stayed at stock height, i never noticed a valve on the rear brake lines, everytime the car was bleed it was up in the air on a lift.
