  • Change brakes

    Need some help to change the front disc brakes on my mini. The nut I need to take the rotors off just won't break loose. If anyone is willing to help let me know. Thanks.

    Do you have a impact gun?

        That nut is tightened at between 188 lb-ft and 200 lb-ft. It's going to take an impact gun or a stout breaker bar and piece of pipe. You also need something to keep the hub from moving. I use a piece of heavy steel channel interleaved between the lug nuts (with the wheel off) so it bears against the floor.

        Good luck and don't hurt yourself,

          Yeah I tried the breaker bar with a pipe over it and interweaving the lugs with something and nothing. I guess I will go get an impact gun tomorrow. Any recommendations on which one to get?

            I think you are on the right path tool wise. Now, Get PB Blaster, the penetrant, and completely soak the nut and all of the threads. Let it sit, then tap the nut and area, NOT steel to steel, and then apply more PB. With the penetrant, time is your friend, so apply Before you get a beer.

            Perhaps you have either a brass, plastic or other hammer to jar it? Maybe even protect the area with a chunk of hardwood and hit the wood with a steel hammer?

            PB is excellent, and it known to be quite a cologne if you plan on going out for St. Valentines Day!

            Best of luck, and let us know how it goes.

                You'll probably need an air impact wrench with torque above 300 lb-ft but I can't say how much higher will be necessary. No experience with electric impact tools.

                  Picked up some PB Blaster and an impact gun. Got one good for 350 lbs. Hope it works. I also got a torque wrench, if I get the nut off what should I torque the nut to? Also with the nuts that hold the lugs on the rotor on should those be torqued to a certain point?

                    Yeah Its not going to happen, still nothing. Anyone got a torch because it looks like that is the only way to get it off.

                    Here is what the left side looks like before I started. The right side is worse.

                      CV nut. Check to see if one hole or two through the CV axle. Two holes: 150 lb.ft. One hole: 188-200 lb.ft.

                      Not sure what nuts you mean.
                      The disc to hub flange bolts: 42 lb.ft.
                      Caliper to hub bolts: 40 lb.ft.
                      Ball joints. 40 lb.ft.
                      Steering tire rod end nut: 25 lb.ft.
                      Lug nuts: 40 lb.ft.

                      All these would be in your manual, with slight variations.

                        Thanks for the info. Anyone have a torch it looks like heat is the only way to brake the CV nut free?

                          If a 350 lb.ft. rated rattle gun won't take that nut off, I suspect you are going to find other problems...or the rating is off.

                          You can cut and split the nut(s), too.

                            I have given up right now, I will try again later. My buddy has a impact gun will see what it is rated for and try it. Won't get back to the brakes until the end of the week when he has off on Thursday or Friday.

                              So I went down to Group 2 and had them brake the CV nuts loose for me. Really nice group of people to have work done on the mini. Will definitely have them work on my mini again if I can't do it myself. So tomorrow I will be changing my brakes and removing my tint on my back windows.
