1994 SC auto with ABS and Traction Control
Need to replace the rear metal brake lines due to failure caused by corrosion. After 24 years and 176,000 miles I can't complain, but don't look forward to doing this job for fear of having to do the ABS Module bleeding.
I've made certain all the lines will come loose, but before I disconnect completely want to know if bleeding the ABS module will be necessary. After reading various links about bleeding the Mark IV system I got the impression the module is bypassed during normal operation and all the internal valves are closed. I could have misread the threads and my understanding in error. If I'm correct, I'm thinking the ABS module bleeding might not be needed.
The master cylinder has not run dry yet.
For reference I'm replacing the lines starting at the bottom of the front drivers side tire at the big 22mm union.
1. Will it be necessary to bleed the ABS module using the required "special" tool if replacing these lines?
2. Any ideas on where to rent a special tool to do the ABS bleed process?
3. Any suggestions on how to plug the fitting, so air isn't introduced? If I knew the fitting type/size at the connector, plugs could be purchased/fabricated ahead of time and be installed immediately after disconnecting the lines.
4. Does anyone know the fitting sizes and end details (double flair or bubble flair) so I can purchase tubing ahead of time? Never had any luck double flaring brake tubing, so will buy the premade type.
Thanks in advance for your help.
