I have recently replaced the front brake pads and flushed the entire brake system. I left the old rotors on, they looked pretty good. At speeds over 30mph the rover brakes fine but an slow speeds It crawls to a stop instead of abruptly. I have had the ABS light on for a while. The brake pedal feels normal.

A few anomalies every couple of weeks the brake pedal will shudder than stop it only does it once at the first brake application. usually in reverse.

Second I have tried the jumper method of 5 and 15 on obd ii port to get ABS codes with no luck. Cant get the lilght to blink codes?

Any suggestions to these problems?

I also found this .pdf that recommends 4 pin and 15 pin be jumped.Dont know if this is correct. I'll attach it.

 

Open the hood, on the passenger fender is a fuse box, open it, remove the ABS PUMP fuse, close fuse box, close hood, no more shudder at the brake pedal.
The shudder is the ABS working when its not supposed to.
As for the not stopping hard, I assume it used to.
It sounds like there might still be air in the lines.

 

Ok so soft braking resolved. Spike thanks for advice. Read a post that said that energizing the ABS while bleeding the system may help get the air out of the ABS pump. So re bleed the entire truck,with the key in position II. Must be dumb luck, But it seem to do the trick. I have no Idea why that would make a difference.

 

I dont either but sometimes air gets stuck in the valve block of the ABS unit.
