How much torque do you need for rotor bolts?
Like most other fasteners used on your bike, rotor bolts have a recommended torque. SRAM/Avid states that its rotors should be tightened to 6.2nm (55 in lb), while Shimano recommends 2-4nm (18 – 35 in lb) for its rotors.
How much torque do you put on brake caliper bolts?
Because caliper bolts MUST stay on, they need a LOT of torque. AutoZone, for example, recommends 113 pound feet of torque. To put that number in perspective, the average person can, according to NASA, apply about 15 pound feet with a bare hand.
Do you need to torque brake calipers?
You don’t really need a torque wrench if your just doing brakes. The only bolts that you need to be careful about are the caliper bracket bolts and they just need to be tight. Torque wrenches allow you to tighten lug nuts without damaging the rim.
How much is 40 Nm of torque?

| 30 | 3.4 |
| 35 | 4.0 |
| 40 | 4.5 |
| 45 | 5.2 |
How thick are Shimano brake rotors?
Shimano rotors are made 1.8mm thick and should be replaced when the thickness has been reduced to 1.5mm. Since 2010, the 1.5mm minimum recommended rotor thickness has been printed on Shimano rotors.
What size torque wrench do I need for brakes?
Brakes really don’t need a torque wrench to service, and in most cases, with adapters and sockets, you can use a 1/2″ for something like brakes. A 1/2″ torque wrench is mandatory to do wheels, axle nuts, etc. If you’re doing anything on the engine, then you’ll probably want a 3/8″.
Which way do you turn to loosen brake caliper bolts?
Basically, (at least on the passenger side) you should be pushing the ratchet down and away from you (towards the rear of the car if you’re facing the rear) to loosen the caliper bolts.
How tight should you tighten caliper bolts?
Over torquing the caliper guide pin bolts: Caliper guide pin bolts typically need a 13mm wrench to remove. It is a rookie mistake to go nuts on these bolts and break the heads off. Typically these bolts require only 25- to 35-ft/lbs of torque. Be gentle!
Do tire shops use torque wrenches?
Every tire job involves removing the tire from the hub, then affixing it again. So, for every tire job, you must deliver a discrete, specific amount of torque to each nut—which means torque wrenches are indispensable equipment for every tire shop.
What kind of bolts do you use to remove brake rotors?
T-45 for the rear disk, T-40 for the front disk. I used one that was slightly too small on the rear disk once without heat, and snapped the bit, no damage to the bolt. I use a hammer hand impact and Snap On or Mac Tools bits and I have never broken a bit or stripped a screw head.
Is it better to replace a rotor or wheel?
IMHO a set of $30-40 driver bits in a drawer is better than having to replace a rotor, or wheel if the bolts snap off. I’m trying to think, but nothing happens!
What kind of Torx bit to use for brake rotors?
Heat the hub up to 400*F to break the loctite and use a good torx bit in the bolt heads . I’ve used a heat gun on several occasions to heat the hub up . Make sure the size is correct as well. T-45 for the rear disk, T-40 for the front disk.
How much torque does a caliper bracket need?
Torque ranges can vary from 30- to 110-ft/lbs. Also, some bracket bolts can be torque-to-yield or require liquid tread lockers. 7. Over torquing the caliper guide pin bolts: Caliper guide pin bolts typically need a 13mm wrench to remove.
