Honda SP1 Front Brake Caliper Strip, Clean, Inspect. Corroded Pistons, No History

Front brake caliper strip down on my Honda SP1 (RC51) 25 years on, no rebuild history, and the pistons tell the story. In this video I disassemble and deep clean both front calipers, explain what corrosion actually does to piston movement and seal function, then make the call to send the caliper halves away to have the factory style gold powder coat renewed before final rebuild. If you’re into proper workshop process, inspection, methodical strip down, cleaning the seal grooves correctly, and making parts decisions based on condition, this one’s for you. What you’ll learn / see in this episode Real world diagnosis: How you can read piston condition and seal areas when there’s no service documentation. Piston removal method: Why I removed these mechanically (yes, it takes effort,especially in a cold workshop). Seal function explained: Each piston runs two seals, hydraulic pressure seal and dust seal—and both are critical to feel and retraction. Why corrosion matters: It increases friction, interferes with seal “rollback”, causes sticking/drag, and can lead to uneven pad wear and heat. Refinish decision: Why I’m renewing the gold powder coat on the split caliper halves before rebuilding for a factory-fresh finish. Parts debate: I’m still deciding whether to replace the pistons, condition and sealing surfaces will decide, not guesswork. Why I work this way (and why it matters) Quality workmanship: Same mindset I use on customer caliper rebuilds clean, inspect, measure, and only rebuild once everything is right. Performance + reliability: Brakes aren’t the place for shortcuts, especially on a bike with SP1 pedigree. The SP1 was built with racing in mind, when the braking system is right, the whole bike feels sharper and more controlled. Chapters 00:00 - Introduction + why these calipers are coming apart 00:45 - Initial inspection: corrosion, age, and what it suggests 01:40 - Mechanical piston removal (the “cold workshop workout”) 03:00 - Two seals per piston: hydraulic seal vs dust seal 04:10 - How corrosion affects piston movement and brake feel 05:20 - Deep clean: bores, grooves, and prep for rebuild 06:30 - Final plan: gold powder coat refresh + piston decision Safety note Brakes are safety critical: If you’re not confident, get a qualified mechanic to inspect/repair your braking system. Cleanliness is everything: Dirt in seal grooves and damaged piston surfaces can cause sticking, dragging, leaks, or poor lever feel. Would you replace these pistons, or reuse if the sealing surfaces clean up well? #HondaSP1 #RC51 #VTR1000SP1 #MotorcycleMaintenance #BrakeCaliperRebuild #WorkshopLife #MotorcycleBrakes #HondaMotorcycle#MechanicLife #asmr
