Hi, even though they appear to be allen heads on the calipers, and they will fit but are a little loose or not at all, they are torx Heads. They look like almost like a star with more points on them. They come in sizes like t-20, t-25, up to t-50. To get the correct size for your caliper, call the dealer parts, and ask. You may have to purchase the right one from them. I saw this happen many times on other autos and trucks, using the allen wrench and rounding out the head. I wish you the best and please be kind when rating me if I have been of help to you.

What size allen wrench do I need to remove the front brake calipers

I'm not sure of the size. I have an allen socket made for GM brake calipers!! But i would guess it is a metric size, maybe a 12 mm. Call an auto parts store and they can pull the tool and tell you with a phone call. Good luck.

What size allen wrench for brake calipers on 2001 Dodge Dakota 2WD 3.9L and what size is the nut holding the rotor on? Standard or Metric?

a 7 mm hex head wrench for the caliper bolts. the nut that holds the bearings in place is usually a 1 inch or 1 1/16 inch, but a pair of pliers should be enough to take the nut off after the cotter pin is removed. when you put the nut back on DO NOT over tighten it or you will damage the wheel bearings.

What size wrench to remove brake calipers

Usually about 9/16. It should be SAE not metric, but if the standard is slightly loose, then you may be best off switching to metric socket.
