Is it possible to remove Bracket bolts without removing caliper pins?
I need to remove both caliper and bracket from a 2003 G35. The problem is one of the the caliper pins is stuck and rounded. If I remove the bracket bolts, will the caliper be removed as well without removing the pins?

Experienced mechanics share their insights in answering this question :
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.

No, never, and there`s no reason at all why they ever would be. Caliper bolts don`t secure a component that rotates. Calipers are stationary, rotors rotate.
The caliper is attached to the steering knuckle via mounting bolts and the caliper sits over part of the brake disc or rotor.
Caliper mounting bolts attach the caliper bracket to the steering knuckle in both cars and trucks.
The steel caliper bolts screws into the aluminum carrier. Anytime you mate steel and aluminum, you should use anti-seize to prevent corrosion and galling the threads.
Bolt Basics
Most bolts have a right-handed thread and turn in a clockwise direction as you screw them in. If you look at the threads of such a bolt, they appear to angle upward to the right (this is called pitch). Reverse-thread bolts have a left-handed thread and turn in a counter-clockwise direction when tightened.
Let the bolt soak for at least five minutes before attempting to remove. Make sure to remove it in the correct direction. Note: While we`re all taught that lefty-loosey – righty-tighty is the preferred method, some brake caliper bolts are reverse thread.
Disc brake calipers are resilient brake components and are expected to last as long as your vehicle. Your brake calipers realistically last anywhere between 75,000 to 100,000 miles or 10 years.
Some signs that your vehicle may have a bad brake caliper can include abnormal noise, reduced braking ability, fluid leaks, or the feeling that your vehicle is pulling to one side. Unlike brake pads that should be replaced consistently, calipers ought to last with the vehicle.
When Installing Caliper Bolts, Torque Each Bolt to 55 ft. lbs.
The caliper guide pins are two round metal pins on each brake caliper where the brake piston assembly sits. They`re called guide pins because they`re responsible for guiding the proper angle for how the brake pad meets the rotor.
Anti-seize products are applied to bolts, fasteners, flanges and other clamped interfaces to prevent galling, seizing and corrosion, as well as lubricating to ease disassembly.
Luckily, tightening a loose brake caliper is a simple process. The calipers are likely loose because they were put on incorrectly. To be safe, you should remove the brake caliper bolts completely. As this part of the car rusts easily, you may need penetrating fluid to get the bolts off.
Uses and Applications of Left-Handed Threads
Left-handed threads are also known as reverse threads. These threads are used in specialized applications in which the application of pressure would force a right-handed screw or bolt to come loose.
Caliper Rattling
If a piece of the caliper is loose or worn out, it can cause a rattling noise.
Torque the caliper mounting bolts to 47-62 ft. lbs. (63-84 Nm). Add fluid and properly bleed the brake system.
Caliper guide pin bolts typically need a 13 mm 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.
Snug is fine. Caliper bolts are loaded in SHEAR, which means a force they experience is trying to cut them off as if they were being decapitated. The tightness of the bolt IS important, but not as important as the strength of the bolt to resist the shear forces.
If one side is damaged, then replace the calipers on both sides. If only one caliper is replaced, you may experience brake imbalance between the front wheels and tires. The new brake caliper may apply the brake pads to the rotor more quickly than the older caliper.
Brembo`s brake pads produce less dust (while providing better bite). That means Brembo brake pads last longer than OE brake pads. You`ll get to enjoy even more savings!
If the caliper or caliper pistons become stuck, it is unable to properly squeeze the brake pads against the rotors, which may cause you to feel some vibrations when you hit the brakes.
A clunking noise from under your car while braking at lower speeds doesn`t mean it`s the end. It does mean that there may be an issue with your car`s braking system –usually a worn-out part. More specifically, a clunking noise when braking can be due to worn or damaged discs, rotors, calipers, and backing plates.
These are made from Grade 5 (6Al/4V) Titanium. Titanium is better than stainless steel and aluminium fasteners because it is stronger, lighter and is completely corrosion proof.
The brake caliper is made of cast iron but can be also made of steel, stainless steel or aluminum.
Advantages of 4-Piston Calipers
Better Heat Dissipation: The larger surface area of the 4-piston caliper`s components also acts as a larger heat sink. With better management of that heat you`ll experience less brake fade on long, steep descents.

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.

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.

Broken Calliper Pin Bolt
ANSWER : Hello, thank you for writing in. The caliper mounting bolt is not necessarily a "specific bolt". You can use another bolt if you have one. There are a few things you want to keep in mind. The first is that you want to do your best to match the threads on the bolts. With that being said, if you screw in another bolt with a different thread size, you will damage the threads on the inside of the mount. Also consider that you do your own maintenance, and if your put in a bolt with a different sized head, you are always going to need a different wrench or socket for that one piece. It may be a pain to get the exact bolt, and you may need to use another in the mean time, but you should attempt to find an exact replacement eventually. They are typically only a few dollars depending on where you live and what you have accessible to you. For more help, contact our service department.

Removing bolt from red current line connected to the car’s battery.
ANSWER : The square headed bolt is designed to keep the bolt from turning when you are trying to tighten or loosen the nut on the other side. To loosen the nut on the other side you will want to turn it to the left. There is a very old saying that uses the acronym "righty tighty, lefty loosey" that is usually a good rule of thumb. There are certain cases where things will have what are called reverse threads where this is not true and is in fact the opposite, but generally speaking, this is usually a good rule to remember.

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.
