Why are the pads on my caliper not working?
The pads won’t fit because the piston in the caliper hasn’t retracted far enough, the piston needs to be pushed all the way home. Front caliper pistons are usually easy to retract, a channel lock or c-clamp will do the job or pry them back using a longish screwdriver.
What do you use to retract front caliper pistons?
Front caliper pistons are usually easy to retract, a channel lock or c-clamp will do the job or pry them back using a longish screwdriver. The proper tool is called a wind-back tool and while it isn’t necessary for front pads, it is useful kit. Force the piston home on front calipers.
How are brake calipers fixed to the carrier?
The calipers are free to move laterally across the caliper carrier. This free movement offers more evenly braking force over both sides of the rotor. The caliper is fixed to the carrier by two sliding pins, the pins are lubed and allow for smooth caliper action.
What causes your brake pads to not fit?
Corrosion can cause all sorts of braking problems, including: 1 Noisy brakes 2 Hard brake pedal 3 Ineffective braking 4 Sticking brake caliper 5 Smoke from brake caliper 6 Excessive brake pad wear 7 Uneven brake pad wear 8 Brake steering issues More …

Why does my car have a sliding brake caliper?
If it’s a sliding brake caliper, it’s probably corroded slider pins causing the caliper to “drag” and stick. This is very common on aging cars, especially if the slider pins weren’t properly cleaned and lubed when the brakes were last worked on. It it’s a fixed caliper with opposed pistons, it’s likely corrosion behind the seals.
Why is a caliper piston not retracting completely, making?
If this is the case you may have a internally swollen /restriction in the flexi brake hose. The master cylinder will easily overcome the restriction to apply pressure to the caliper but some of the pressure will be trapped upon releasing the pedal.
Where are the pads on a brake caliper?
Most brake calipers will have identical pads, you could use them inner or outer and left side of the car or right. However, some will have a specific pad for inner and outer. But be mindful some could also have inner, outer, left and right side of the car.
What causes brake pistons to retract?
As others have stated, the piston seal is the only thing that retracts the piston. Corrosion in the caliper, a collapsed brake line, incorrectly adjusted brake lever, clogged or blocked ports in the master, oil in the system, or even problems with the reservoir cap can all cause the caliper piston to not retract properly.
How do disk brake pistons retract?
Some pistons simply retract by slowly squeezing the piston into the bore. This can be done with the disc brake caliper piston tool set or even a large C-clamp. Place the wedge plate from the set onto the drive arbor of the tool. Insert the bottom of the drive arbor into the caliper piston.
Why do brake calipers stick?
One of the most common reasons why a brake caliper gets stuck is the combination of caliper piston and brake hose . Normally, the piston can work thanks to a rubber boot lubricating and protecting. However, the rubber will torn after time, causing rust and debris to form inside the caliper.
