Why do you need to remove the sliding pins on a disc brake?
Video tutorial on how to remove and lubricate the sliding pins on a disc brake assembly. Sliding pins, also known as guide pins allow your caliper to float, so when your brake pedal is applied, the braking surface on both sides of the rotor can be used.
How to lubricate caliper slider pins-YouTube?
Loosen caliper mounting bolts & slider pins , remove caliper, grease slider pins, re-assemble. If the caliper is defective – click here to see how to replace the caliper
What causes a brake pin to get stuck?
There are several possible causes. Something could be wrong with the brake line or piston. But often the problem is a stuck caliper pin. One or both of the little rails the caliper slides along — the caliper guide pins — get sluggish or seized. And that means your caliper won’t slide, and the outside brake pad won’t fully squeeze your rotor.
What to do if your caliper pin is stuck?
The next idea is both clever and simple. It uses the bolt that goes into the end of the caliper pin as a lever to simply force it out. A YouTube mechanic going by the name Alpha G Male has a video in which he puts washers and a coupling over the end of a stuck caliper pin on a Nissan Altima.
How do you fix a stuck brake caliper?
One way to keep your brake calipers from sticking is to give them a good spray with brake cleaner. There are times when road dirt, brake dust, and other particles will get into the calipers causing them to “gum” up and stick. Brake cleaner will help penetrate into the calipers and loosen them up.
How do you Grease a brake caliper?
Lubricate the caliper slide pins with the white lithium grease. Reinsert the brake pads and put the brake caliper back into the caliper bracket by hand. Thread the caliper bolts in by hand and then tighten them with the socket set.
What causes calipers to freeze up?
One way a caliper can freeze up is by the piston on the caliper being stuck in its bore. If the dust boot that protects the piston from the elements gets torn, water and debris will penetrate the metal in the caliper and cause rust and corrosion.
What is a brake caliper guide 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. On the next page, we’ll explore how to determine whether or not your brake…
How do you change the brake pads on a bike?
Use a straight-blade screwdriver to screw in the brake pad pin cover until it is tight (most model bikes). Roll the rear tire with your left hand and push down on the rear brake pedal continuously with your right hand until the piston completely pushes the brake pads against the rotor and stops the rear tire from rolling.
What happens if your brake pads wear out?
Allowing the brake pads to wear into the metal backing plate will cause serious damage to the brake rotor. Inspect the brake pad thickness periodically and more often if you ride in muddy or sandy conditions. With the bike sitting firmly on a stand, locate the rear brake caliper.
When is the best time to replace brake pads?
Brake pads should be replaced once the thickness in any pad is less than 1mm. Allowing the brake pads to wear into the metal backing plate will cause serious damage to the brake rotor. Inspect the brake pad thickness periodically and more often if you ride in muddy or sandy conditions.
What’s the best way to replace brake pads?
Step 21 – Install new brake pads into the caliper bracket while keeping the stabilizer clips in place. Step 22 – Some brake calipers utilize a pressure clip which should be replaced if provided or damaged, these clips help hold the brake pads securely while not in use.
How do you install a retaining pin on a disc brake pad?
Install any retaining pin. On systems with a cotter pin, make sure to give the cotter pin a good bend to prevent it from sliding out. On systems with a threaded retaining pin, be aware of any torque specification from the manufacturer. In general, the pin should be snugged to the caliper body.
What’s the mistake of not cleaning the brake slides?
Not cleaning the brake slides and hardware: Just slapping new pads where the old pads once resided never works. The slides and abutment clips should be cleaned and/or replaced. 2. Not lubricating the guide pins: Caliper guide pins on floating calipers should be cleaned in solvent and new grease should be applied.
How do you put new disc brakes on a car?
For mechanical disc brakes, after installing new pads you will need to align your calipers. For hydraulic disc brakes, pump the lever to move the pistons and pads back to the working position. Pump until you feel the pads firmly contacting the rotor. Spin the wheel and inspect the pads for alignment. If there is no rubbing, you are done.
