Brake failure! (1 Viewer)

[2001LC]

I cleaned up the connection a bit just so I could see what I am dealing with.

No way to use the heads of the screws as they are....so I cut a slot in each one:

A flathead screwdriver is now a good fit, BUT if they don't break loose easily in the morning after soaking in penetrating oil, then I'll probably have to grind the heads off. Looks like there are nuts underneath the posts and I don't want to break the plastic or twist off the post connections.

Got the new Master Cylinder rebuild kit installed without any trouble, but this is going to be a challenge.

Soaking may work for.

I've just been drilling the heads off. The trick is to not damage the lead wrapping over the nuts.

Here's one place, I posted drilling them.

Grease is for things that need to move... Bolts need to move...LOL The grease you see me using today is Red-N-Tacky. I use marine grease (MG) also, but the MG stuff I've been getting lately has been to thin. This Red is designed to hold in place without breaking down, doesn't wash out and has...

Thanks Paul,

Found that earlier.

Thinking I will carefully grind them down with a dremel if I can't just unscrew them. But I imagine the rust is likely spread through the threads and nut....so not expecting that to work really (unscrew them).

I'm a bit surprised they didn't use stainless steel in that area. Unless a person packs the rubber cap with dielectric grease or other corrosion inhibiting product....then I'm not so sure the cap is even a good idea. I saw no evidence of brake fluid having ever gotten in that area or having spilled over. I believe it gets moist under the cap from condensation then rust sets in.

Thanks for the link and input, appreciate it.

Flint.

So did mine..... until the next day. Working on mine today, by coincidence. I was shocked to see how corroded the wire connections were at the ABS unit. Not too bad at the motor but at the ABS unit you can't even tell these are screws. Not even sure yet how I am going to get them off.

What do you mean by "until next day"?

What do you mean by "until next day"?

Meaning I had an ABS light and warning buzzer one day, the brakes were fine and had plenty of pressure, light went out and all seemed fine. Next day it came on again and I lost ALL boost just driving from my house to my shop.

Point is: IF you've had the ABS light on and/or warning buzzer, heed that warning and look into the system to see what the trouble is. It isn't a 'fluke' and the issue will only get worse possibly leaving you with a no brake boost situation.

In my case i did't get any light or warning buzzer while driving i only lost by braking for once. I do get light and alarm set off while i was pumping paddel with ignition on.

Bottom Line:

If you lost braking (ever) for ANY reason, then check into it.

Man those wires are pretty much gone.
And btw i found this wire under accumulator.
Looks like it is recently unpluged.
