Removal of front left Caliper on S4RS

[DucRS]

I'm removing the two bolts that hold the front Caliper on so I can remove the front wheel.

The Right Caliper came off easy, counter clockwise.

The Left Caliper will not budge, counter clockwise.

I'm wondering if the Left Caliper has reverse threads? Before I apply any more pressure I need your help.

(while sitting on the bike, right and left sides)

Thanks!

I cannot imagine that an S4RS would have reverse threads on the caliper... the only reason for reverse threads is if there is rotational force applied directly to the fastener (like in some hubs).

How big is your implement of removal (saying "tool" there just felt wrong)?

I applied approx. the same pressure on left as on right plus a touch more and nothing.
It may be the shop torqued the left more than the right. I Just don't want to ruin anything.

I'm using a socket style wrench with an Allen head.

Bolts are right hand thread both sides.

More muscle or more leverage.

Snapped! It was on tight.

Thanks guys!

Perhaps the right was under torqued and/or they didn't use thread lock on that side and did the other.

If you're using the 'normal' length 3/8" ratchet, those bolts should be pretty hard to get moving initially. They should be torqued to 35-38Nm. While not HUGE torque it's pretty good and if you're not using something with a longer handle it requires a good bit of a grunt to get there.

FWIW - this style of ratchet has become a favorite in my arsenal. They take a little getting used to with the flex neck - but they have a longer handle length, flex neck and if you're mechanical ninja skills are up to it you can get it working a bit like a hand drill style speeder bar. Turn the head 90 degrees to the handle, put your palm on the butt of the handle and crank it like a hand drill

I believe no lock tight on replacement just the special grease.
