Bravo 12BST HP repair

Like most people I bought the bravo pump because pumping the floor to high-pressure was such hard work
I purchased it back in 2009 and had two years of good use out of it before it broke.
All the broken ones I've seen have gone on the pins that the high-pressure pump cogs run on.
I first fixed it in 2011 and have just replaced the brass sleeves now.
It's run fine for all that time although you can see that the old brass sleeves have got a bit hot at some time the pump has always worked.

How I repaired mine, although I'm sure there are better ways.

Strip the pump down, remove the bolts that screwed into the old pins. Tap the hole all the way through M4. Cut two M4 bolts so the end is just proud of the cog, 5MM brass tube from model shop or eBay. Cut length to fit inside the cog fill tube/bush with grease wind screw in.
Finally just make sure the pistons are on opposing strokes.
It's not pretty but has and still is working well.
I use my pump for a Kayak as well a Sib and a van awning baffle so it gets used loads
Hopefully this will help a couple of people from throwing their broken pump away

Yep interesting 212 thanks... I hope not to see the inside of my similar age Bravo too soon but if the time comes good to know a bit of thoughtful DIY might save the day.
