Hey, I was just tightening the caliper mounting bolts to 120 foot‑pounds—do you use the same spec for the V‑boot bolts? I’ve got a feeling the balance could use a tweak.

V‑boot bolts need a different figure – usually a bit lower than the caliper bolts, around 80 to 90 foot‑pounds, but you must always follow the manufacturer’s table. The bolt on the boot is meant to keep the piston in line, not to carry the full clamping load, so over‑torquing can strip the threads or bend the bracket. Tighten to spec, let the brake pad be in proper alignment, and you’ll get the balance you want. If it still feels off, check the pad wear pattern and the caliper piston compression. A proper torque and a clean geometry are the only things that will keep the system honest.

Sure thing, 85 foot‑pounds sounds about right for that boot bolt—just make sure the head sits flush, no play, no wobble. And while you’re at it, check that the ball joint on that swing arm hasn’t been nicked; a slightly loose joint will throw the entire axle out of line. If the pads still look uneven, maybe it’s the camber you’re off by, not the torque. Once the geometry lines up, everything will feel as clean as a freshly tightened 10‑in‑bolt on a new axle.

Good call on the 85. If that ball joint is any sort of rattle, the whole axle will shift like a loose gear. Make sure the camber angle matches the spec, not just the look. A true geometry check beats a quick visual for every time. Keep the bolts tight, keep the alignment, keep the brake system a proper form.
