Torque Specs
Caliper Bracket Bolt: 125ft/lbs. Rear Guide Pin: 26ft/lbs.
banjo bolt and crush washers to the caliper – Torque to 35 ft-lbs.
When Installing Caliper Bolts, Torque Each Bolt to 55 ft. lbs.
Instructions: Do not lubricate bolt. With two new crush washers installed, torque bolt to 96 – 120 in-lbs. (do not exceed 144 in-lbs).
The nut holds just the axle in the hub and to the flange. With these types of hub units, they typically have lower axle nut torque specifications that can be between 85- and 170-ft. lbs. The torque specification can also vary due to the diameter and size of the rolling elements.
The heavy-duty front brake caliper bracket has a torque specification of 275 ft/lbs. The rear caliper bracket for the heavy-duty caliper has a torque specification of 163 ft/lbs for the upper bolt and 190 ft/lbs for the lower bolt. Both versions have a torque specification of 32 ft/lbs for the guide pins.
Mounting the brake on the motor end allows a smaller brake to be used, but it`s still important to properly calculate the torque required to hold the load. Determining this torque requires working backwards from the load using this formula: TH = (T/GR) * K.
Banjo bolts in 6mm, 10mm, 12mm, 14mm, 16mm, (as well as 8mm extra-long bolts), 1.5mm banjo bolts, 12mm pipe fitting 14mm banjo bolts, bulb primer/banjo combinations,180° double banjos, single thread banjos, 90° double and triple banjos, 5/16th` 10mm banjos with 1/4` and 5/16` stem, 10mm with 1.5 pitch and 12mm with 1/4 …
Torque the caliper mounting bolts to 47-62 ft. lbs. (63-84 Nm). Add fluid and properly bleed the brake system.
As for the caliper, it`s also good technique to use a torque wrench. The main reason is so you don`t over-tighten then, which might strip out the housing the bolt goes into, or ruin the mounting bolt in the first place.
Snug tight torque shall be between 10% and 20% of the torque listed in Table B2. 3. Match mark the bolt tip, nut, and the plate in a straight line.
DETERMINING TORQUE
The general equation for bolt load based on applied torque is T = KFiDb where K = torque coefficient. K is a function of the coefficients of friction and collar friction in the joint, and these are based on variables such as surface finish, coatings, and so on.
The front brake caliper bracket should be tightened to 70 ft/lbs and the rear should tightened 85 ft/lbs. The caliper bolts have a torque spec of 44 ft/lbs and 23 ft/lbs in the rear. Pressure bleeding is highly recommended to bleed this brake system to ensure all air is removed from the system.

I need the torque specifications for the caliper bracket bolts, banjo bolt, and caliper slide bolts.
ANSWER : The caliper bracket bolts are 125 ft lbs. The banjo bolt for line connection is 35 ft lbs. The caliper slide bolts are 26 ft. lbs.
Is it possible to remove Bracket bolts without removing caliper pins?
ANSWER : The complete bracket and caliper can be removed this way. I have seen this many times where the caliper retainer slide bolt seizes. The reason is no one lubed the slides and pins when they did the brakes in the past. This was avoidable if they lubed them on previous brake jobs. You can also purchase a new caliper with the bracket in most cases as an assembly. If you want to have a mechanic assist you with this, a certified technician from YourMechanic can come to your car’s location to inspect your suspension and help perform this task.
I am doing the water pump. first 5 bolts came off. the middle driverside bolt is blocked by a bracket. how do I get bracket off?
ANSWER : I would recommend looking all around the bracket for all mounting hardware that attatches it to the engine. Once all mounting hardware has been found, you can then loosen and remove the mounting hardware in order to remove the bracket. Once the bracket has been removed, you should then be able to remove your water pump. If you are in doubt about this repair, I would recommend seeking the assistance of a certified mechanic.
My truck won’t go up into Park there’s a bracket that is connected to the shift linkage cable and on that bracket I need to replac
ANSWER : Unfortunately, the only way to remove bolts that have broken off into a metal hole is to drill them out. Depending on the amount of space available, certain parts may need to be removed to gain access for a drill. This may involve removing the transmission all together. I would recommend having your truck inspected by a qualified transmission expert to determine the best way to approach removing the broken bolt.
starter switch replaced and do you have the computer to reset it. Also need help to put my new gas tank in. I have taken all bolts
ANSWER : Hello. After replacing the ignition switch on your vehicle you should be able to reprogram it manually. Putting the key into the ignition and leaving it there for a few seconds until an indicator comes up on the dashboard saying “key teach in progress” . After doing that 3-4 times the vehicle should start up as normal. We may be able to get a technician out to you today depending on what area you are in. I will inform customer support of your need for assistance right now but it may be beneficial to call 844-249-6752 and use their call back feature to get the fastest assistance possible.
Ignition coil bolt can’t bolt down
ANSWER : The valve cover on that side of the engine has the broken bolt boss. The only way to secure the coil is to either replace the valve cover so you have the bolt boss to bolt down the coil, or to change the coil involved in the misfire.
How do you remove the torque converter bolts off the flywheel? 2005 GMC Envoy Denali
ANSWER : Hello – with the vehicle safely supported to provide clearance underneath – in between the engine oil and transmission pan, there is a large, funnel-shaped aluminum casting (called the bellhousing), that physically mounts the engine to the transmission. At the forward vertical face of the bellhousing (immediately behind the engine oil pan), is an access plate – remove it. The engine flywheel/flex plate is now exposed. There will be 3-4 bolts, which go through the flex plate to the torque converter, which hold the torque converter to the engine flywheel/flex plate. Turn the crank from the front crankshaft pulley bolt (CLOCKWISE facing the nose of the engine) a bit, remove a bolt, turn the crank a bit further, remove the next bolt, etc. until all the torque converter bolts are removed. At this point, you should be able to slide the torque converter toward the rear of the vehicle 1/4-1/2" by hand. This will confirm that all bolts are out. You will also be able to rotate the torque converter by hand, without turning the engine. Remember this when re-assembling the engine/transmission, and it becomes to rotate the torque converter to line up the bolt holes in the flex plate. Proceed with the removal of the transmission.
if I need brake pads, rotors, and calipers, how long can I wait before I get the calipers? is it ok to just do the pads and rotors
ANSWER : Hello.
While it would be easier to have them all done at the same time, you can wait to replace the calipers if you need to. Keep in mind, however, that performing a flush requires you to open the brake’s hydraulic system. So if you plan on replacing the calipers later, the system will have to be re-opened and re-bled when the calipers are installed. In most cases calipers only need be replaced if they malfunction, usually in the form of a seized piston or leaky seal. I would recommend carefully inspecting the calipers when the brakes are done to see if they even need to be replaced.
