What is the bore on a wheel cylinder?
The bore or inner diameter of the hole. You could pop a piston out and use an open end wrench measure it. 13/16″ is .
What’s inside a wheel cylinder?
The wheel cylinder consists of a cylinder that has two pistons, one on each side. Each piston has a rubber seal and a shaft that connects the piston with a brake shoe. When brake pressure is applied, the pistons are forced out pushing the shoes into contact with the drum. Wheel cylinders used to be made of cast iron.
What causes a cup seal to move back to its original rest position?
The outward movement of the caliper piston during brake application causes the piston seal to distort. Once the brakes are released however, the seal returns to its original shape forcing the piston to retract in its bore.
Why is the master cylinder reservoir split into 2 separate units?
This is to allow for fluid level changes as the disc pads wear. Inside the master cylinder is a machined bore that contains the master cylinder primary and secondary pistons. Both pistons are combined into a single, two part unit.
Which brakes are better disc or drum?
Disc brakes are always better than drum brakes and can deliver excellent braking performance. The disc brakes might cost you a premium, but the kind of braking performance you get is worth the money. We recommend you to go for bikes with disc brakes and ABS as it will protect you during panic braking situations.
Why are drum brakes still used?
Drum brakes lock-up the wheels easier and make better parking brakes than disc brakes. Those who enjoy doing handbrake turns may also favour rear drum brakes since they lock-up easier (self-energizing). Drum brakes are also smaller and lighter but these are not reasons why modern cars still use them.
What would occur if the star wheel adjuster from the left side was put on the right side?
What would occur if the star wheel adjuster from the left side was put on the right side? The star wheel will function normally. The brake shoes will self-adjust away from the drum surface. The brake pedal would have no free-play.
Why do my rear drum brakes lock up?
One of the most common causes of one or two wheel lockup on drum brake equipped vehicles is the service and/or parking brake adjustment. If the parking brake system is not de-adjusted properly before the brake shoes are adjusted it will cause the rear brakes to engage too soon.
Can I use regular grease for brakes?
Brake Lubricants 101. 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 you use white lithium grease on brake calipers?
Re: white lithium grease can be used as brake caliper grease? Lithium grease is typically not for high heat applications. Something designed to withstand high temps of brake systems you should use. A good anti-seize will do both, keep parts from seizing together and work as a brake lube.
Is Lithium Grease OK for brakes?
White lithium is a low-temperature grease that can be used to lubricate drum brake hardware and backing plates, but lacks the heat-resistance for front disc brake applications. So it’s not the best choice for general brake work.
What kind of grease do you use on brake pads?
So it’s critical that you use synthetic high-temp brake pad grease to lubricate the caliper pins, pad abutments and pad slide hardware. Now there’s a new type of grease made especially for ceramic brake pads (one choice is Permatex No. 24125 Ceramic Extreme Brake Lubricant; about $17 for 8 oz.
What is white lithium grease good for?
White lithium grease is used to keep components moving smoothly, free of friction and seizing. You can also apply it preventatively to protect against rust and corrosion. White lithium grease can be used to: Lubricate car door hinges.
What is the grease that comes with brake pads for?
Super Lube® Silicone Lubricating Brake Grease can also be used to dampen vibrations between disc brake pads and caliper pistons. It should NOT be applied between the pads and any noise suppression shims. Use it sparingly on the back of a bare pad or between the pad shim and caliper.
Where do you put the grease when changing brake pads?
Brake Lube ensures noise-free braking and proper system operation. A thin layer of brake lubricant is that is needed. Apply lubricant on caliper pins, clips, edges of the brake pad mounting tabs, and back side of the brake pads if needed. *Do not apply lube on the friction side of the brake pads.
Should you grease brake pistons?
You should not have to lubricate the brake pistons. If you are replacing pads you should clean & lube the pistons.
