Convert system TC and ABS to conventional brake system

[edc1967]

Query, it is possible to eliminate the P38 brake system and convert it to traditional system, without compressor or ETC...

I check that the original system has many problems, and there are very few spare parts, so was thinking about change and place a traditional system.

I check that the original system has many problems,

Really? The ABS system on a P38 is about the most reliable part of the car.
Check out the D2 section if you want to see real ABS problems.


I can't see why you couldn't convert it though. The physical side would be easy as the brake assy is mounted on a separate body plate which is bolted to the firewall so you could remove that to test fit a conventional booster.
You'd need to investigate what the BECM needs from the ABS ECU to fool it. I think the vehicle speed is picked up by the ABS system too.

I suspect that a change such as this to the braking system would need engineering approval - and be unlikely to get it.

Do they worry about such things in Chile?

doable, th easiest way is just to unplug the main feed to the BS pump.

its going to throw error codes and lights as you tho.

Also as far as I am aware, its illegal, by the letter of the law, in any country to disable an oem fitted safety feature on a vehicle how enforced that is is questionable.

It's as simple as this:

1. Pull the ABS relay from the engine bay fuse box.

2. Remove the ABS lamp bulb from the dash cluster.

Job done.

EDC wants to get rid of the pressure pump. To be able to stop the car, he'd need a vacuum booster.

However, it might need a bit more work. I recall reading that the P38A has no rear brakes when the brake pump isn't working. Without power boost, the car is very hard to stop.

The hydraulic system comprises two completely
independent circuits, with a vertical i.e. front/rear split.
The combined POWER and HYDROSTATIC CIRCUIT supplies the front calipers.
The POWER CIRCUIT supplies the rear calipers.

I have had a pump fail, I can confirm it's very hard to stop

IHello. the truth is just an idea, the problem is that if the modulator fails no spare, well, I disassemble the modulator and change the orring of solenoids, these were bad, succeed in eliminating leakage, full arm the advised system for relative who is an engineer, the problem is that to hit the brakes this produces a rejection ...

it gets hard and strong brakes ... they said they might have air in the brake circuit or a bi-directional solenoid that is failing and puts pressure on the pedal ...

for that reason he had thought of converting the system to a traditional ... for lack of spare parts.

you could run a vacuum pump off the back of a suitable alternator, mechanically it should be fairly straight forward, it's just how the computer would react
