A Tesla iBooster electrically actuated brake booster and master cylinder assembly, part UT-1044672-00-D. Supplied untested.
An iBooster replaces vacuum entirely. A conventional brake servo needs engine vacuum, which a conversion has to recreate with a pump, a reservoir and a switch. An iBooster is electrically actuated: a motor provides the assistance directly, so there is no vacuum system at all.
That is a cleaner answer to the problem, and it is what modern production electric cars use. It also gives you brake blending: because the boost is controlled rather than mechanical, a controller can coordinate regenerative braking with friction braking, which is how an EV recovers energy without the pedal feeling odd.
It is also considerably harder to integrate. An iBooster expects to talk to a vehicle that knows what it is doing. It is not a bolt on replacement for a vacuum servo, and making one work in a conversion is a serious piece of engineering rather than a plumbing job.
This one is supplied untested. We have not verified its function. For a development project, a bench setup or someone who intends to test it themselves, that is reflected in the price. It is not a part to fit to a car's braking system on trust.
Key specifications
| Part number | UT-1044672-00-D |
|---|---|
| Type | Electric brake booster and master cylinder assembly |
| Actuation | Electric, no vacuum required |
| Vehicle | Tesla |
| Condition | Untested |
| Weight | 0.5 kg |
Features
- Electric actuation, so no vacuum pump, reservoir or switch is needed
- Controlled boost, which is what allows regenerative and friction braking to be blended
- The approach modern production EVs use
Compatibility
For development work and conversions prepared to engineer the integration.
Untested, and this is a braking component. Have it tested and proven before it goes anywhere near a vehicle that will be driven. If you want a straightforward answer to losing engine vacuum, our brake vacuum kit does that job with a conventional servo and is far simpler to integrate.
Ask us what you are getting before ordering. The assembly's condition, its exact variant and what it needs to be commanded are all things we should confirm for you rather than have you discover.
