Front Disc Brake Pads | Honda CB350G, CB360, CB450, CB500, CB550
Italian-made replacement front disc brake pads for vintage Honda motorcycles with hydraulic front disc brakes. These semi-metallic pads with brass and bronze content replace the original pads that have been sitting for decades. Direct fit, sold as a pair.
Why You Need This
Original brake pads on these bikes are over 45 years old. They harden, glaze over, and lose their grip. Pads that have been soaked with brake fluid from a leaky caliper piston seal tend to crumble — the friction material separates from the metal backing. Either way, they need to be replaced.
The set includes two pads — one thicker (piston side) and one thinner (opposite side). This is the Honda factory design. These pads are also included in our caliper rebuild kit.

Model-Specific Notes
- CB350 K0–K4 and CL350: These have drum front brakes — you need brake shoes, not pads.
- CB350G (1973 only): The G is the disc-brake variant of the 350 twin. Confirm your bike has a front disc before ordering.
Installation
Apply a light coat of disc brake caliper grease to the back of each pad and the caliper housing recesses.
Frequently Asked Questions
Does this fit my Honda CB350?
Only if it's a 1973 CB350G with a front disc brake. The CB350 K0 through K4 (1968–1972) all have drum front brakes and use brake shoes instead. Look at your front wheel — if there's a caliper and rotor, these fit.
Why is one pad thicker than the other?
The thicker pad goes on the piston side (inboard) and the thinner pad sits on the opposite side. This is the Honda factory design.
Should I replace anything else while I'm in there?
If your caliper is leaking brake fluid or the piston is sticky, the caliper rebuild kit includes new pads plus a piston seal, bleed screw, and crush washers.
