  post locked   2002 Grand AM brake line questions  

Alright so I have an 2002 Grand AM with 250,000 miles and shes getting pretty rusty and ratty(Minnesota car). I have plans to replace the brake lines here in the next week or two as a precaution. What I need to know, does it use double flare or bubble? Does the pressure module have to be used or can I run right off the master and T it? One of my hub sensors stopped working about 2 years ago so I don't have ABS or trac control and that doesn't really matter to me(never used to have cars that had it anyway).

Thanks

It could have either bubble or flare or a combination of both. You will find out when you take them out. You need to be prepared for both.

I'm not sure what you are saying about the ABS but if it was equipped with ABS, there is no way to bypass it and you may in fact have to have it working to be able to bleed the system as it is bled electronically.

That is my pressure module/abs controller. I have a wheel hub sensor that has failed and disabled both abs and trac control. I was wondering if I could just bypass that and put a tee in both the rear and front brake lines off the master to feed the calipers?

Did you not read what I just posted?

No, you cannot and you will need it to electronically bleed the system with a scan tool.

Yes, I did read what you posted. If the fluid is not going through the ABS system I should be able to just bleed the system like any other vehicle without ABS right? Basically the lines will be going straight from the master cylinder to the calipers so I don't see how it would need to use the electronic bleeding procedure. All I really needed to know is if I do it this way will not using the ABS system cause any other issues besides not having ABS?

You aren't going to get any advice here on modifying your brake system.

The only advice you will get here is to return the system to factory stock.
If you have any questions on how to do that this thread can continue, otherwise it will be closed.

You're welcome.
From your response, I assume this thread is no longer needed so I will close it.

Just to add the anti-lock control system can't be eliminated because it also serves to control the proportioning of the rear brakes through dynamic proportioning.


Quote
Dynamic Rear Proportioning (DRP)
The dynamic rear proportioning (DRP) is a control system that replaces the hydraulic proportioning function of the mechanical proportioning valve in the base brake system. The DRP control system is part of the operation software in the EBCM. The DRP uses active control with existing ABS in order to regulate the vehicle's rear brake pressure.
The red brake warning indicator is illuminated when the dynamic rear proportioning function is disabled.
