Ram / Dodge Brake Fluid: ABS Bleed and Why You Should Not Mix DOT

Why Ram trucks need this more than people think

Brake fluid absorbs water. On a salted-road Ram that sits, the fluid is often the cheap insurance you skip. A flush is not a pad job.

Rules

  • Match DOT 3/4 (or whatever the cap says). Never mix DOT 5 silicone into a hydraulic ABS system.
  • Keep the bottle capped. Old open fluid is junk.
  • Many RAM ABS modules need a scan-tool bleed. Two-person gravity bleed may leave a long pedal.
  • If the pedal sinks or the ABS light stays on, stop. That is not 'more fluid in the bottle.'

Spongey pedal after a DIY bleed = air, leak, or the wrong procedure. Brakes are life-safety. Informational only. EZ Car Fix is not a shop.
