I believe that is 7mm Allen key.
your going to need a t-40 torx socket.
Remove the caliper and the rotor just comes off. Might have to us a hammer and bang it a few times.
Its time to replace it.
Take off brake caliper and then hit the rotor with a hammer near the wheel bearing to break the seal between the rotor and axle shaft
look at the bracket where your rear veiw mirror attaches to the windshield,,, ok then on the bottom side there is a little hexagon screw,,,take it out with a small Allen wrench,,then slip the rear veiw mirror up off the steel base that is glued to the winsheild itself,, you should have no problem
Front brake job. 1994 ford tempoWhen you pull the tire off take a #T30 Star Key not an Allen key to remove the brake caliper. Check the rotor see if its needs to be cut or replaced. Put your freshly cut rotor on or new rotor on. After this take a C-Clamp and a socket (any size deep recommended) and start tightining the C-Clamp to recomprese the piston on your caliper. If the caliper doesn't easly comprese the piston is seized and your going to have to replace the caliper, if the piston compreses put your new brake shoes/pads on starting with the rear pad (the small one) then the front (the bigger one). Slide the caliper on and tighten the star keys and your done. P.S Take the caliper off starting with the top first then the bottom and do the exact opposite to put it back on.
Have to remove the transmission.
with a motor dolley
Place (locality) ... remove 'l' to get pace (tempo)
Follow top rad. hose.
cliff notes: Jack up the car Wheels removed 2 bolts on the back of the caliper Slide caliper off the rotor being careful not to let it just hang remove brake pads put new ones in possibly having to compress pistons using a c clamp (inside of the caliper) to make room for the newer "thicker" brake pads clean EVERYTHING while you have it all open Turning the rotors at the same time is suggested and...reverse
there is a pin on the switch which must be depressed to remove the unit from the dash.
