Hi, my name is Mitchell, This is my first street bike. 1986 450c rebel. I've ridden dirt bikes my whole life and a few street bikes of friends but I've had this bike for a few weeks and already dumped it because the front brakes locked up after building up tons of heat without me knowing. After the ER and a few days of healing, I took them apart and cleaned the master out and flushed the lines clean and took out the Pistons. The O rings are bad so I'm trying to find a new Master and a new caliper instead of rebuilding the one on it that's damaged from the fall. It bent the bleed valve and inner threads.

I'm looking for help on finding a new caliper, highway bars, and handlebars. I've seen the Honda vt1000 has the same kind of pegs and wish I knew which other parts will fit. Right now the bike has a dent in the tank, some valve tapping and the carb needs rebuilt and cleaned but it fires right up. The front brakes are what's stopping me from riding it, just from fear of it happening again even though they seem to work fine now.
Sorry for the long introduction, hopefully I can find the questions here that I'm looking for.

I plan to strip it down soon to rebuild the carb and then learn how to adjust the valves. I'm somewhat mechanically inclined with vehicles but not motorcycles. I've never rebuilt a carb or adjusted valves but downloaded the manuals with instructions.
Highway bars are really what I want to find first because it sucked having my leg stuck under it when it fell. Lol.

Welcome to the forum. Have you taken a basic street riding course?

Look here: 1986 Honda CMX450C A FRONT BRAKE CALIPER | Cheap Cycle Parts

The entire caliper is no longer available, but the seals and O-rings are. You may be able to take the old O-rings to a store and match them up.
The sell the rebuild kit on eBay for 30 dollars which is kind of expensive so I'll try the local hardware store. The calipers on eBay say they fit my bike and look very similar.

doubt you will find square cut caliper piston o-rings at hardware store..
Square cut o-ring is required to draw back piston when pressure is released..
bottom of caliper piston seal grove is angled and must be cleaned out well..
pressure on piston distends/deforms square cut o-ring, when pressure released seal springs back drawing piston with it away from disk..

$30 for 2 piston seals and 2 dust seals isn't that expensive imho..

braided stainless brake line will improve braking substantially over rubber lines which have a tendency to deteriorate interiorly especially after 30+ years..
