ABS isnt the only thing you need to look for ... does your van have speed censors ?

The hydro boost just helps pressing the pads , thats normal

there are speed censors on the rotors ... I bet it does ... these are different from the Vehicle Speed Censor, that one is on the side of the tranny...... these are ABS Speed Censors
My '92 & '93 has them .... but when they made my 93 a 4x the ft rotors dont have the censors N thats why my brake light has been on for 17 yrs.

Symptoms of a Bad or Failing ABS Speed Sensor
The ABS and or brake Light comes on. The most obvious sign of a problem with the ABS system is that the ABS Light will come on. ...
Brakes take longer to stop car. ...
Less stability under icy or wet driving conditions.

The anti-lock braking system is designed to apply smooth application of brake fluid to engage the brake calipers and pads to slow your van without locking up the tires. The wheel speed sensor is responsible for relaying the wheel speed to the ECU so that it can tell the ABS system how much pressure to safely apply.

A red BRAKE light, or an amber ABS light? Some have both.

When lamps do you get with the key on, engine off?

I got in one day and my light came on.got a $30 box off a pickup. Fixed mine. I mean that black box under the left fender,right above the battery. I might even paid too much. That box fits about a zillion GMs.

Got a pic of it? Where you are talking about its a bit of a mess on my van.

As far as the light, the light comes on as soon as you turn the key, before the engine starts and stays on after

NOT as bright as when the actual parking brake is applied, but RED and fairly bright

Open the hood, look above the battery to the right under the inside of the fender. It's about 4x6 and an inch thick. Black plastic box.
