1111 Mazda Miata NA/NB Brake Bleeder Adapter – 70mm Threaded

The Motive Products 1111 Miata Adapter is a 70mm threaded, red-anodized aluminum adapter purpose-built for the first and second generation Mazda Miata (NA: 1990–1997, NB: 1998–2005). The 70mm ATE-style threads engage the Miata's master-cylinder reservoir cap for a leak-free, positive pressure seal — enabling one-person brake and clutch bleeding without makeshift solutions or constantly checking for leaks.

Vehicle Fitment

• Mazda Miata NA – 1990–1997 (1.6L and 1.8L)
• Mazda Miata NB – 1998–2005 (1.8L, including NB2 Mazdaspeed)

Not for NC (2006–2015) or ND (2016+) Miata — those generations use a different reservoir profile. The 1111 is specific to NA and NB.

Key Features

• 70mm Threaded Fit – precisely machined to engage the NA/NB Miata master-cylinder reservoir cap threads; holds pressure without seepage.
• Red-Anodized Aluminum – corrosion-resistant finish matches the Miata's enthusiast aesthetic.
• Quick-Disconnect Compatible – snaps onto any Motive Power Bleeder tank via stainless quick-disconnect.
• Brake & Clutch Bleeding – seals on both the brake master cylinder and clutch reservoir caps where applicable.
• One-Person Operation – pressurize to 15–20 psi and bleed all four corners or the clutch line solo.

How to Use

Thread the 1111 adapter onto the Miata's reservoir cap, connect your Motive Power Bleeder, pump to 15–20 psi, and bleed each caliper or clutch slave bleeder in sequence. Essential for track-prep brake flushes, brake system rebuilds, and clutch hydraulic refreshes on NA and NB Miatas. Pair with any Motive Power Bleeder tank for a complete one-person system.
