Do you have to torque brake calipers?
For some parts like the caliper bracket-to-knuckle bolts the torque is pretty high, like 90 ft lbs and there are tons of stress on those bolts, those must be at the correct torque.
What are the disadvantages of double piston calipers?
The only disadvantage of using double or triple piston caliper is added number of leakage sources. Another factor that affects performance of a caliper is pad wear. It seems that pressure exerted by the pads is even over the pad area but it does not happen in practice.
How does a fixed type brake caliper work?
• Fixed Caliper Fixed type caliper has pistons on both sides of the rotor and can be directly fixed to the mountings on the uprights. Pistons from both the sides force the friction pads to apply force on brake rotor. Fixed caliper does not require extra mounting bracket which is necessary in floating type caliper for sliding.
What are the features of AP Racing calipers?
STANDARD CALIPER FEATURES. ◘Differential Bores and/or piston positioning are used on all AP Racing multi-piston calipers to combat pad taper. ◘High Temperature Seals are standard on all AP Racing race (com- petition) calipers. ◘Hard Anodised Surface Treatmentis standard on all AP Racing com- petition calipers for optimum durability.
What causes uneven wear on a brake caliper?
In calipers with multiple pistons, pad area is greater along the circumference of disc resulting in significant uneven wear. In multi-piston calipers the pistons are different in diameter such that the smaller piston is on the leading side and the greater one on the trailing side.

What happens when the piston of a brake caliper is engaged?
With a retracted piston, the car may pull toward the side of the car with operating brakes when they are engaged. You may also notice that braking distance increases. Conversely, an engaged piston will cause the car to pull toward the engaged brake when driving.
Which is better a floating or fixed brake caliper?
The major advantage of fixed caliper over a floating caliper is the even wear of the friction pads. A floating brake caliper is generally preferred as it has multiple advantages over the fixed caliper. The piston being only on inboard side occupies less space on the outboard side.
What happens if you have a bad brake caliper?
The latter can result in brake failure. A damaged piston, or one that is simply corroded, may get stuck in one position. If it sticks in the retracted position, that wheel will lose braking ability. If it sticks in the engaged position, the wheel will brake continuously until freed.
