1970 Honda CB750K · Caliper Rebuild Parts Buying guide

Compare a caliper kit with individual piston and seal parts

The featured kit combines several small caliper parts, but the replacement piston has its own listing. Identify the items requiring replacement and compare their dimensions and applications before adding duplicate service pieces to an order.

Avoid duplicating the small service parts

The kit includes the sealing ring, caliper bolts, bleed screw and cap, plus adjuster hardware. Compare it with the individual pieces already in your order. The replacement piston is offered separately.

Use the piston dimensions alongside the caliper identity

The separate piston description provides diameter and length, which are useful checks against the removed component. Those dimensions do not replace identifying the caliper itself. Have its condition and required repair assessed, and use the service manual for the appropriate inspection and service specifications.

Questions that help you choose

When does the kit make more sense than individual pieces?

Compare the parts needing replacement with the kit’s contents. It combines seal, bleed and adjuster components; the individual listings allow a narrower order when those other pieces are being retained.

What should I check if the front end has been replaced?

Identify the caliper fitted, including any markings and the existing piston dimensions. Use that assembly’s application when choosing internal parts; the motorcycle’s 1970 year does not establish the caliper’s identity.

Why should I compare the piston length as well as its diameter?

The replacement piston listing specifies both 38.15mm diameter and 34mm length. Use both stated dimensions as comparison points and confirm the caliper application. Choose based on the fitted component rather than only one measurement or the motorcycle year.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
