I wrecked the abs sensor the first time I put in new strut cartridges, etc. Since, I disconnect the connector under the hood, pull it out the wheel well, and wrap it around the lower part of the strut and secure it with tie wraps. I know this doesn't help you now. You can probably get new sensors on ebay or Amazon or just replace the strut assembly with one from a junkyard. The price may be about the same and 740 strut assemblies with aba work okay, 1991 and later.

It is probably best to remove the brake caliper and pads so you can twist the caliper loose from the hose.

Good luck!

The sensors are difficult to remove especially if corrosion is evident. When they refuse to come out I have used a drill (3/8" ?) to remove the innards and then went after the rest with small chisels and screw drivers. It involves separating the thin metal shell from the opening it fits into- tedious and time consuming work. Lots of penetrating fluid and patience required. It would be easier to do on the bench then when the assembly is on the car. The best course of action would be to unplug the sensor and remove the strut assembly.

The brake hoses are usually difficult to disconnect on the end that attaches to brake line. If you have the connection to the caliper loose you can remove the caliper and rotate it until it is disconnected from the hose.

If you have a stick of the correct length you can push the brake pedal down part way and hold it there with the stick. This will put the master cylinder piston in a position to prevent the fluid from leaking out with the brake line open.
