If one was to do there breaks for the front, is there anything special needed?
Like from reading some say the top calliper bolt is a pia ??
Can you use a regular ratchet or normal wrench?
I think flash said to use a curved 14mmm/ 9/16 wrench,..,but is that necessary ?
I have had pads kickin around forever and really should pop em in.....lol I'm sure works better that way, hehe
I got the caliper opener tool today, 5 buck tool... Also (not including polar bears time frame,heheh)
How long should one expect to do, relaxed, 1.5?

Re: Front brakes?
The left top bolt is a PITA!
I used a ratchet wrench (9/16 I think it was) but the special curved wrench would be better...especially if it was a ratchet one.
Its pretty straight forward after that for the front. Spread/inspect/reinstall.
The rear is more work as you need to drop the skid cage and deal with the parking break but it's otherwise not too bad man.
I did take the corners off the new pads as the guys say to keep them from chattering and it worked fine.
Funny you posted this today Monk as I noticed my brakes were squeaking a bit on the way to the dealership to check on the wife's H3 which is under the anesthetic yet again! (Ball joints..etc)
Have fun

Re: Front brakes?
Ya , was wondering if a regular wrench would work...
Luckily had my rear brakes done last rear ,
Got my rear callipers and my diff seals off Roys Shop, but forgot to order those little star washer seals, soooo always had a little diff leak and , again the star seal is on a to do list one day soon, topping the diff up monthly sucks....(well with Ont, winter temps, hehe)
lol, same as you mine were squealing a bit yesterday am, and figured I should break down and do them, last time was they were changed was like 5 years ago, but I figured a straight forward job.,

Re: Front brakes?
Maybe the abs are different? As mine are non abs
I went under to look at the job to "tackle" the caliper bolts are Allen key heads (not sure on size yet)
I then googled some pics of front caliper pictures are the Allen kind as well...., seems semi decent for wrenches....lol, Shockingly "I was expecting worst'
Only thing I noticed is one caliper looks newer, but the other caliper ,the bleeder screw looks ,hmmmm like it's been there a while... Almost not sure if it would turn, I hope....

Re: Front brakes?
The Allen Head bolts are the slide pins. The black bracket is the one that has the 9/16 bolts that hold everything in place. It is far easier to remove the black bracket with the caliper!
