1977 Honda CB550K · Brake Caliper Rebuild Kits, Caliper Pistons, Bleed Screws Buying guide

Choose a repair package after identifying the caliper

The repair kit itemizes seals and hardware, while the piston is a separate dimensional choice. The aftermarket assembly names its included components and notes that final assembly may be required before installation.

Compare the kit contents with the needed components

The one-caliper kit supplies a boot, seal, two O-rings, snap ring and two washers. A replacement piston is separately offered. Compare the assessed caliper pieces with that itemized list before buying both a kit and additional seal hardware that might duplicate what it supplies.

Check the supplied condition of the assembly

The aftermarket assembly lists the body and several internal or attached parts, including pads and bleed pieces. Its description also says final assembly may be required. Check that supplied condition and the contents when choosing the complete unit, then use the necessary service information for the brake work.

Common ordering questions

Is a piston named in the repair-kit contents?

The itemized repair-kit list names a boot, caliper seal, two O-rings, snap ring and two washers. A piston is separately listed. Compare that contents list with the assessed components before planning a piston purchase.

What dimensions identify the separate piston?

Its description gives 38.15 mm diameter and 34 mm height, with Honda reference 45107-323-020. Check the fitted caliper and removed component against both dimensions and the reference before selecting the replacement piston.

What is included in the aftermarket assembly?

The description names body, pads, piston, piston rubber, bleed screw, bolts and bleed cap. It also notes possible final assembly before installation. Compare those supplied pieces with the required repair rather than assuming an already assembled condition.
