Honda-SOHC

Hi,

Right so I got myself in a bit of a mess when trying to bleed my rear brake as I was loosing a lot of pressure - it just wasn't breaking unless I pumped the brake at least 20 times.

The top part of the bleed nipple was broken and whilst trying to get out the remainder of the hollow screw with an easy-out, the easy-out broke staying stuck in the hollow screw. I tried to drill it out, using titanium drill bits but it didn't do much good and if anything I've now made a bad situation worse.

I spoke to a Nissin specialist who told me that basically the only way to do anything about it now would be to go to a spark erosion specialist - but he said they're expensive and would easily cost the price of a caliper - which is my other option.
Now this particular model of Nissin caliper (the stock one of my 77 CB750, I believe it's the 9V3 model) is not easy to come by. There are a few kicking about on ebay but I doubt that they would come in very good shape.

So I have a few questions:
- Has anyone used a spark erosion specialist and could share their experience (and perhaps details, particularly if they're in the London area)
- Has anyone replaced an identical caliper and if so with what.

I'm really looking for some input as I've been using only my front brake for the past few weeks and I really can't keep this up much longer!
Thanks!

Dear members, fellow bikers and bikeresses,

It began about 3 months ago when I woke up one morning and decided that I couldn't carry on riding my Tmax (that's a 2010 500cc scooter by Yamaha) everyday to work. The Tmax works fantastically well, it's got a boot to store a full face helmet, a leg cover for the cold and rain, it's low maintenance, it's ideal to commute on but.....it's sooooooo boring!
I've been riding everyday (or just about) for the past 12y, had several bikes (several Yamaha fazers, a Suzuki SV), several scooters more recently, and had convinced myself that bikes (and manual gears) where not adapted to commuting.
All that went out the window that morning when I decided that I needed a ride with character, something with a soul that would be like an extension of myself. Perhaps it's also because in a couple of years I'll be 40, but that's another story...

I eventually set my mind on a Honda CB 750 - mostly because I like the builds of Steelbent customs. I found a 1977 F1 with 15,000 miles on ebay and bought it. It's just spent 2 months with Rex at Victory/Untitled in Camden who did a great job on it and kept my it to the budget agreed. I picked it up 2 weeks ago - it's fantastic, my life has changed! It's great to ride and when it's parked I can't stop looking at it !

Pic attached - although there has been another mod today when I had Rex fit a K model oil tank, it looks much much better, I'll upload another pic soon.

I have a several more modifications in mind and will look forward to getting advice and guidance from the forums.
Perhaps someday I can even contribute!

Thanks
Rimmer
