1993 W124 300D Brake Line Replacement
 

During the course of my strut/shock replacements I noticed that all four rubber brake lines are VERY cracked.

I occasionally have a mushy brake pedal as well.

The master cylinder/fluid reservoir looks very new suggesting to me that the previous owner replaced them.

My question is can I just unscrew the existing brake lines and replace them or is there some process where I have to bleed the ABS system?

Replace the rubber lines, then bleed the system normally.

Thanks, the deed is done.
