ABS light on after long storage, new SS brake lines installed

I replaced rear calipers and added SS brake lines all around while car was down.
I bled the entire system and brake pedal was very firm.

Car was down for years, so could be corrosion on rings?

I started up car today and brakes felt normal, but the ABS light is on along with the brake light.

Suggestions? I did do a search but nothing came up.

Probably air in the abs pump. Try activating the abs on loose gravel and then re-bleed. If it will activate. Not sure if the light being on will disable the abs.

Got a dirt road right by the house. Will try it Saturday.

I just got insurance put back on it today, but can't get to secretary state for a few days to get a new tag.

Thanks for the tip!

Let us know if the abs is disabled when the light is on, clean abs hack!

Procedure to bleed the ABS unit itself? Is there a VFAQ for this?
I did not do this. I only bled brakes at the corners.

I don't believe there is a special procedure for bleeding ABS on this car. I use a vacuum bleeder on mine usually, and have not had issues.

I would check for junk (usually metallic) collected on the front sensor magnets. This can affect the reading.

Sitting for a while it may be a stuck solenoid in the unit itself. Clean fluid and driving it to get the system to activate is a good starter approach. Hopefully if this is it, it will break loose.

If you end up needing a hydraulic unit (if you keep ABS), I think I have one in my collection.

My dirt road is bumpy, too! That could help.
I will also see if I can clean the rings. I could have bumped the sensor on one of the corners as well. I changed out the passenger front half shaft when it was JSBing so I can start there after a quick drive on the road.

Need to get my registration updated. Last tag I had was 2008. Saved over a grand in tag costs that way, at least. /ubbthreads/images/graemlins/smile.gif

I am planning to use the specific year plate program in Michigan when (if?) I get mine back on the road this year. I have a nice pristine 91 blue plate for it.

Delete the ABS IMO. The stuff on our car is 2 channel diagonal garbage, and it barely helps if you brake like a monkey mid corner in the rain. In every context of using brakes properly it simply increases your stopping distance due to the glacial cycle rate.

If I had an Evo, I'd keep ABS, but on these shitpiles, it's a liability. I measured a ~25' shorter stopping distance from 60-0 with some very fast & loose methods, but it was pretty consistent.

The junk is heavy, doesn't work well, and makes the engine bay look like crap. Plus now I have an awesome location for my remote oil filter setup /ubbthreads/images/graemlins/laugh.gif
