Hi, I want to change all my brake rotors and pads. The only concern is for removing the 2 bolt that hold the caliper brake pad. one of the bold it inaccessible and need to have tips to make room for my impact since bold is to hard to remove by ratchet

here is the picture of the bolt.

Thanks

 

Have you tried a universal joint? That would be my best guess. But when I went to work on my rear brakes I just used a wrench and a rubber mallet on that part. Or you can try to increase your leverage when using a wrench is by sticking a pipe on the end of the wrench. You just gotta use brute strength to take the bolt off.

 

Yes,, iirc,, used a impact socket, with an extension or two, and it should come off,,, (if I remember correctly)

 

Once the car is lifted, you need another jack to lift the control arm to make some room for your rachet to fit. An impact gun might be too tight for it to fit. The top bolt is easily accessible, but the bottom needs the control arm lifted.. but be careful when lifting as your jack will be compressing the rear springs...

 

Those bolts should only be torqued to 62 ft.lbs., so they shouldn't need a ridiculous amount of strength to remove. You can just use a breaker bar to increase your leverage AND make sure you are turning it the right way. Bolts like these that are threaded toward you (if you remain outside the wheel well) with their head on the opposite side have a reversed orientation (like in a mirror), so while the old "Righty-tighty, Lefty-loosey" still holds true, you have to do the opposite. I'm not trying to insult anyone, but caliper bolts in particular are a frequent victim of this confusion.

 

James has a good idea but if youre like me and dont have a second jack then all i did was to spray with PB blaster and then stick on the old style regular flat wrench on it and use a rubber mallet to give it a few blows and it came loose quite easy. Like VQ said they are not supposed to be torqued down that hard so a few blows with hammer onto the wrench should break it loose

 

You need a 19mm wrench just changed mine last weekend.

Good luck

 

That's what I do also with a 2nd jack.

 

Oh, make sure you use penetrating oil-damn that shiz sounds weird (or WD-40) scrub the bolts with a wired brush before trying to break it free..
