What is a caliper pin?

What is a caliper pin?

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.

How tight should caliper guide pins be?

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!

Should caliper pins be tight?

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.

How do I know if my caliper pins are bad?

Here’s how you can tell if your brake caliper has gone bad:

1. Pulling to one side. A seized brake caliper or caliper sliders can cause the vehicle to pull to one side or the other while braking.
2. Fluid leaks.
3. Spongy or soft brake pedal.
4. Reduced braking ability.
5. Uneven brake pad wear.
6. Dragging sensation.
7. Abnormal noise.

What grease do you use for caliper pins?

Permatex Ultra Disc Brake Caliper Lubricant is a green, nonmelting, synthetic lubricant. It is formulated to lubricate under the most adverse brake conditions, assuring that metal to metal contact areas remain lubricated throughout the pad life. For use on caliper pins, hardware, and the back-side of brake pads.

Can I use anti seize on caliper pins?

Non-lubricant-rated anti-seize should not be used where relative motion between parts is expected in service such as on caliper slider pins. Most anti-seize compounds are not lubricants, which is a desirable property in many applications.

Can you use regular grease on brake pins?

Can I use regular grease for brakes? That’s why ordinary, general-purpose chassis grease should never be used for lubricating brake components. It won’t hold up. What’s needed is a specially formulated, high-temperature brake grease that can withstand the heat, and also not harm rubber seals or plastic bushings.

Can I use bearing grease on caliper pins?

As long as it’s a fully synthetic grease, you should be OK. Any petroleum in the mix WILL cause the rubber bushings to swell up and lock the pins.

Can I use grease instead of anti seize?

You can use grease quite effectively as an anti-seize compound. It’s not as good in high temperature applications, but there aren’t any of those on a bike. However, NEVER use anti-seize compound as a lubricant.

Should you use anti seize on engine bolts?

Anti-seize should be used when dissimilar metals are involved (steel bolt into an aluminum brake caliper), when threads may be exposed to corrosive effects (suspension fasteners), where high-heat may accelerate corrosion (manifold, turbo, and exhaust fasteners), and on fasteners that frequently get removed (underbody …

Will anti seize cause bolts to loosen?

Adding anti-seize will cause the bolts to loosen and quite quickly. This is due to the extreme vibration of the 2 stroke engine. However using low strength locite not only stops the bolts from loosening, but also slows corrosion.

Is it OK to spray WD40 on electrical connections?

It dries quickly, leave no residue and removes over 95% of common surface contaminants, making it the best at cleaning electrical contacts and for optimal performance of equipment**. Safe and ideal for use on printed circuit boards, controls, battery terminals, switches, precision instruments and electric panels.

Is WD40 bad for door hinges?

WD-40 is a great lubricant for squeaky doors. It can also last for a long time on the hinges before it dries out. Spray some onto the hinges and wipe any excess that drips. This will fix your squeaky door hinges!
