I am looking for the vacuum pump to run a brake booster on a diesel, and heard that possibly MR2 and Estima/Emina vans have an electric pump?

Any truth to the rumours, and if so, how much are they?

Cheers.

Hmm, cant say I've heard of this one before, but i'd be interested to know.

dont think so,

diesil alternators have vacuum pumps, and some vehicles have a specific belt driven pump, but never heard of an electric one??

twin turbo jzs147 aristo's run a electronic/nitrogen brake booster if that helps. my uncle was looking at using one on a kit car at one point...

good point about the mr2..... i know ones with power steer use an electric pump for that, but do they run a vacuum line all the way up to the front for the brake booster, or is it indeed electric?

They run a line to the front, early turbos had a one way valve built into the booster, later they changed that to having one in line.

Don't go anywhere near that system!! My old man just had the one in his car replaced after failing completely (2002 Lexus GS300) - Try $2900!!

The late lucida diesels have a vacum pump on the rocker cover which is run off the cam by an arm on a lobe. Early ones still have a front pump on the alternator
