Front caliper bracket lower bolt

How do you guys access that ***ker on their FB's?

No way a socket fits there

I tought about trimming the mounting bracket a bit so i can at least access it with a wrench.

Wanted to get some feedback first.

Thanks in advance!

Take out the 2 knuckle to strut bolts then you can turn the strut independently from the knuckle.
They're different lengths, make a note of which is front/back, and don't forget to torque them at the end of the job.

I have a Cornwell Tools offset box 15mm and14mm wrench from this set https://webcat.cornwelltools.com/WBM...int-p371692471 that will fit that bolt. Previous to that, I ground down a box end 14mm to get it to fit. So go to Harbor Freight and get some cheap wrenches to experiment with

What I usually do is back it off with a box wrench until just before it's too close to the steering arm to use a box wrench, then use an open end wrench until it bottoms out against the steering arm, then loosen the wheel bearing so the rotor can move away.

I knew a guy who used to remove the washer and shorten the bolt a bit so that you could remove the bolt without moving the rotor. Those strut to steering arm bolts don't always come out.

I wonder if SAs use a shorter bolt? Its a challenge to loosen it initially but then I just back it off until its free and it can fall out.

I haven't done it yet, but I was reading the procedure in the Haynes manual and it talks about having to pry on something to get room for a box end to break it loose. Then turn it little by little with an open end. Sounds like a pain.

At this point, i think the easiest way is still to remove the 2 knuckle bolts to get access unfortunately...

After the first time fighting with it, I trimmed the bracket and never looked back!

I’m in the middle of completely re-doing the front suspension and it’s on less bolt to fight.

not recommending, just pointing out that it works without any problems. If you’re racing or a track car, I wouldn’t do it.

As I recall, I think we did that too on allot of cars. If you install a strut spacer like these access to the bolt isn't an issue: https://technotoytuning.com/evolved-...the-sa-fb-rx7/

This is the wrench I modified. It is an old Bonney 14mm offset wrench. I ground down the top side of the box end to get it to fit.
