ABS DIY?

[ozmdd]

Resurrecting an old thread here - has anyone ever determined how much needs to be retrofitted to put ABS on a non-ABS LB? I've found the pump/control modules for affordable prices, but wondering how much else has to be added, or if the entire braking system is different? Was this a strictly-factory option, or added at the port-of-entry?

Definitely a factory option. Usually there are a number of sensors that go along with the system for feedback you'd also have to get.

It would require the 4 wheel speed sensors (and wiring), the ABS ECU, the Brake Actuator Assembly, a new cluster (if you want the indicator).

I don't think the ECM needs to be changed or reflashed. The reason I say that is that the EPC doesn't specifically indicate a different ECM for ABS.

I've always been surprised at the negative reactions to ABS, as well. Personally I would much rather have a car equipped with ABS than one without, mostly because I realize the limits of my own ability. I'm a frequent autoxer and would like to think that I am at least an average driver. I know that there's a difference between threshold braking around a cone course where I'm looking ahead and anticipating each corner and when someone stops dead in the middle of a freeway, though. I also know that having one brake pedal means a 4-channel ABS system can deal with a situation where I've got two tires on an ice slick and two on wet pavement better than I can.
