Why does Toyota put a vacuum pump on their diesels? The ABS is electric not vacuum. The only vacuum I have found is one solenoid for idle up with AC. If it goes cactus, has anyone disabled it?
GXL HDJ80 Cruiser - Lifted, Locked, 315's, 3" Zorst, Safari Intercooled, High Flowed Turbo, All the fruit. AMMS tuned coal shovel, Pushing 148rwhp... + heaps of the black sooty goodness...
isn't ABS just a fancy DCV controlling the flow of "pressurised" brake fluid to the individual calipers as required by the computer and determined by the axel rotational inputs?
innovation is better, better is faster, and fast is all that counts
I don't know about the internals of the thing, but mine has a hydraulic pump on it. They have a huge resovoir of fluid, so their operation is significantly different from a simple inline pressure control.
I wonder why toyota didn't ditch the vacuum pump as it's not used.
I've often thought the same thing, on ABS equipped 100's the only vac device is the a/c idle up as you say.
I'm sure the vehicle will run fine without the idle up, however your a/c won't be as efficient at idle, and things like the p/s may load up at low speed & low rpm corners (eg.supermarket car park).
Its easier for Toyota to make them all with vacuum....the std 100 still has vacuum booster on brakes, and runs 1hz the gxl would do without it all together, as the 4.2 is hard to stall
