Removing Brake Bleeder Nuts & Valves with the Mini-Ductor® Induction Heater & Flameless Torch

Removing brake bleeder nuts and valves is often a lengthy, difficult and frustrating task for auto mechanics. Nuts securing the bolts rust easily and, as they’re usually placed in hard-to-reach areas, it makes it very difficult to remove them.

However, help is at hand. The Mini-Ductor handheld induction heating tool, uses Invisible Heat® that heats ferrous metal (containing iron), and some non-ferrous metal, parts in seconds. This allows all types of adhesives bonded to metal, bonded with thread lock compound and seized hardware to be removed and released much quicker and more safely than by traditional naked flame heating. And there’s no costly and time consuming damage to surrounding areas.

Garages and technicians do not need to run the risk of using a torch which could damage brake parts, such as the brake line or pipe.

The Mini-Ductor’s bendable coils are ideal for hard-to-reach areas and thin enough to wrap round the nut and heat it in seconds for easy removal. Using the coil, a 3/4″ nut is heated red hot in 15 seconds. If a torch was used, this would take several minutes. The heat expands the nut, breaking the corrosive bond.


Step-by-Step Instructions for Removing a Seized Brake Bleeder Nut

  • Equipment needed: heat resistant gloves, overalls, goggles and a respirator mask (if smoke will be produced from heating)
  • Knowledge required: a well-reviewed proficiency of the tools safety and operating instructions

Step 1: Identify seized bleeder nut and remove plastic cover.

Step 2: Fit proper size coil to bleeder nut. A larger coil will still work, but it will take a little longer to heat. Fit coil to unit and tighten thumb screws.

Step 3: Heat bleeder nut and immediately apply a wrench to unscrew the bleeder nut. Dispose of excessively heated hardware.
