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!
What should brake caliper bolts be torqued to?
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.
What is caliper torque?
Brake torque is essentially the power of the braking system . The brake caliper acts on the disc at a certain distance from the hub center, known as the effective radius. The force exerted by the caliper, multiplied by the effective radius of the system equals the brake torque.
Should you use anti seize on brake caliper bolts?
If you use it on caliper slides they will seize up and become frozen in place. If you use it to lubricate the pads they will also become stuck and not move properly.
Do you grease caliper bolts?
Before putting the caliper bolts back into their spot, they need to be lubricated properly . Brakes are one of the hottest places for your car, so you’re going to need high-temperature grease. This lubricant is synthetic and can withstand the high temperatures that your car’s brakes will reach.
How do you tighten a brake caliper?
Caliper brakes can easily be adjusted using the barrel adjuster near each lever. If the brakes are too soft for that to help, tighten the cable. To fix brake rub, make sure the brake is centered. If it’s loose, squeeze the brake lever to center it and tighten the bolt that mounts it to the frame.
How does a screw in brake caliper work?
There is a cone behind the piston and it moves with the piston when the foot brake is applied. When the parking brake is operated, the brake lever turns the screw on which it is mounted (it also is an an adjusting screw threaded through an adjusting nut). The nut can’t turn because it’s splined into the cone.
How much torque should a banjo bolt have?
Do not lubricate bolt.
With two new crush washers installed, torque bolt to 96 – 120 in-lbs. (do not exceed 144 in-lbs). Torque to lighter specification and check for leakage, increasing torque only to stop leakage without exceeding maximum specification.
Do you need to grease caliper pins?
Before we re-insert the caliper guide pins into the caliper housing, they need to be properly lubricated. But remember, it’s always best to check your vehicle’s service manual before doing this kind of work. You’re going to need some high-temperature grease . ... They should slide right in if you used enough grease.
Can you use dielectric grease on brake caliper pins?
Dielectric grease dies not conduct electricity and does not cure (stays pliable), silicone does not conduct electricity and cures to a hard form. Neither should be used on brakes . Slide pins should use synthetic grease for that purpose. Its better to use synthetic grease on slide pins, labeled for disc brakes.
Can I use brake grease on caliper pins?
It has a non-melting, stable consistency from -55 to 570 degrees Fahrenheit. This non-melting, synthetic grease can be applied on caliper pins, sleeves, bushings, and pistons to keep them lubricated throughout the lifespan of the brake pads.
Should you use Loctite on caliper bolts?
STOC #687. I’ve never used Loctite on the caliper bolts on any bike I’ve ever owned in over 400k miles of riding. Red loctite is the one that is considered permanent and requires a lot of torque and/or heat to remove, so that would seem like total overkill. Blue is probably the better choice if you use any at all.
What happens if you don’t grease brakes?
This lack of lubrication causes a few things to happen. First, because the brakes don’t contact the rotor properly , your brake pads can wear unevenly. Second, the slide pins may stick, causing the brake pad to continually contact the rotor, resulting in a buildup of heat, which wears your brake pads down faster.
Can you use white lithium grease on caliper pins?
Don’t use lithium grease . Don’t use expensive grease with a needlessly exotic formula. Braking for cars and motorcycles is what is considered safety critical.
Why is there rubber on caliper pin?
A Theory: The Brake Caliper Slide Pin Rubber Is an Anti-Rattle Device. ... The sleeve provides additional friction , which prevents the brake caliper from rattling/chattering within the confines of the caliper bracket. It works similarly to a shock absorber, where it slows down and dampens the movements of the calipers.
What happens if your caliper is too tight?
If one of the front calipers is stuck closed, you may notice the vehicle start to pull to one side . If one of the front calipers is stuck open, you may notice the vehicle pull strongly to one side under braking. ... The front brakes do the vast majority of the braking on most vehicles.
Why wont my caliper piston go back?
Open the fluid reservoir before using a screwdriver to push back the piston (Rear caliper – use wind-back tool). If the piston fails to retract, suspect a frozen caliper , but one other possibility remains a collapsed brake hose.
Is silicone paste the same as dielectric grease?
Dielectric grease and silicone paste are essentially the same thing . Although various additives may be added depending on its intended use (automotive,marine, etc.) they are both made predominantly of silicone; silicone is made from silicone oil and fumed silica.
Can you use wheel bearing grease on caliper pins?
Wheel bearing grease – not the best. You wouldn’t be happy if your local Mechanic used it. The best lubricant is one that withstands high temperatures, doesn’t attract dirt, and is friendly to rubber components. Synthetic disc brake lubricant such as this one will work just fine.
Can I use copper grease on caliper pins?
Never use copper grease there , and lithium grease can attack some rubbers/plastics.
Is plumbers grease the same as silicone grease?
Plumber’s grease is waterproof and comprises of silicone oil (polydimethylsiloxane) in combination with silicone grease. It’s a dielectric grease in nature, but is relatively thicker than regular grease. ... It’s commonly used by plumbers when installing O-rings and faucets.
Can I use SIL Glyde on spark plugs?
When applied to spark plug boots and wires, the product prevents boots from sticking to plugs and distributor cap. It also prevents voltage leakage. Avoid stuck-on boots & Prevent arcing.
What part of the brakes should not be lubricated?
The brake pads press against the rotor or drum in the wheel, whether it’s a drum brake or a disk brake. ... An ordinary lubricant would actually melt in these conditions, and could then run or splatter onto other parts of the brake system, including the rotor or pads. Slippery brake rotors won’t work.
Can Vaseline be used as grease?
If the only lubricant during assembly is Vaseline, go ahead and use it . Petroleum jelly comes from the same oil base as regular grease. It is always advisable to go for bike grease or regular automobile grease if it’s not an emergency.
Why do you put grease on brake pads?
Brakes are made up of a lot of moving parts and these parts need to be lubricated with brake grease to make sure that everything operates as it should do. Applied correctly – brake grease will prolong the life of the brakes by reducing everyday wear and tear .
Is Copper Grease good for brakes?
Copper Grease is an excellent conductor of heat and when used on the backside of a brake pad can significantly increase heat transfer. ... Never use Copper Grease on the back side of a brake disc mounting face as this can increase the Disc run out lead to DTV (Disc Thickness Variation) causing brake judder.
What is the difference between red and blue Loctite?
