Honda CB750 Front Brake Caliper Refurbishment | Motorcycle Brake Rebuild | Part 23
In this Honda CB750 project bike episode, I rebuilt the front brake caliper on my CB750 build. I am building this bike to be a road-going runner, not a full restoration, so I am giving it what it needs rather than aiming for perfection. As I have mentioned before, a working front brake is essential for my health and happiness :)
Here's what I used in this video:
Red Rubber Grease: ebay.us/Blydfz
Brembo DOT 4 Brake Fluid: ebay.us/XOl6z1
EBC CB750 K0-K6 Brake Pads: ebay.us/ZglFDC
Goxawee die grinder rotary tool: ebay.us/qYyEoZ
Wire Brush: ebay.us/VjE0ns
Although very seized and covered with corrosion, this caliper cleaned up quite well. It doesn’t have any damage to any of the important parts, like the threads or seal seats.
I have used a new piston as well as a new seal. I always use red rubber grease to build up calipers. I used to dip it all in brake fluid as a lubricant, but that risks damaging any paintwork it touches, so this is a lot less risky.
I bled the brakes using the traditional method of; get some pressure in the line by pumping the lever and holding it; then open the bleed valve; let the brake fluid and air out; close the bleed valve; then release the lever; repeat. I have tried using a syringe to backfill the system, but I haven’t been overly successful with it yet!
Although I do get pressure in the system and I am sure that all of the air is out I am still not completely happy with the front brake, so I will have to investigate further.
