Anyone know of one that'll fit in there?  Wilwood has a couple that might fit -- best one looks to be 260-8794 but at a little over 7" long it may be too long.  Wondering what else is out there.

I have enough pedal to test drive this weekend but will need to swap the master before really driving it around.

What insurance did you end up with Rob?? Ageed Value and how many miles a year?? Or did you do an Agreed value on top of normal insurance?

I'm shopping around right now!

Sorry for being off subject.

No worries Calvin.  I haven't insured it yet -- need to get it out of the garage to send pics which I'll be doing this weekend when I do the 1st test drive .  Am going with ANPAC/Chrome.  Declared as Modified/Custom; 10k mile/yr restriction; $21K agreed value; 300/500 liability; $500 deductables for collision & comprehensive.  Right about $400/yr.  Requires it not be a daily driver; must have other primary vehicles for each driver in the household.

Runner up was American Collecors -- 7.5k mile limit (they call it "Freedom level"); same valuation & generally the same restrictions but $1000 deductable.  Initial quote came back at $499/yr but it didn't note it was modified.  When I asked them about that they said it was quoted as a standard MGB & sent an updated quote -- $915/yr.

Rob, I like the 1" Corvette style in the Speedway catalog,probably in Summit and Jegs also.Meant for 4 wheel discs and fittings can go on either side.That is for newer pedal box. For older models I use dual masters with balance bar. You can also look at some import ones(Toyota,Nissan,Subaru) that look similar to stock at rockauto.com. Maybe 79-81 Nissan 280ZX 15/16".You could use remote reservoirs. Banjo fittings (probably 10mmx1.0) to IFF to residual valves to existing lines.Silver Mine Motors has best price at $85. Looking forward to seeing the car pics!

That 79-81 Nissan 280ZX 15/16" one looks good Jim.  Looks to be the same casting as the Wilwood one I found @ Summit (although Wilwood's is 1") at about 1/2 the price.  Looks like a re-man one goes for as little as $45 too which makes it worth trying out if it's not too long.  About the only think I could see that would be better is if the ports were on the other side.

Is there a way to search RockAuto or some other site using specs like bore diameter, dual circuit, etc.?

Rob, I don't know if this will work but, it gets good reviews. Meant for 4 wheel discs. 93-95 Non ABS Toyota 1" FJ80-built in residual valves.V6 Pickup,FourRunner,Land Cruiser,T-100 truck. Only the FJ80 Land Cruiser has built in rear residual valve as it has rear discs stock. Would have to drill 4 holes for mount and open up original opening.Looks shorter than Wilwood and cap is forward.

Rob and Calvin,

I just got a quote last week from Hagerty. 300/500 liability, 500 deductible, 25K agreed value, collector plates, nondaily driver, for 360/year. They know it is modified and they are OK with it still not having an interior or most body panels. I went with them and didn't call anyone else because I used them in the past (I never had a claim though).

Hagerty's policy has pretty tight usage restrictions -- at least the policies they write in TX do (each state is different).  In TX the policy only includes hobby use -- parades, going to/from a club mtg or repair shop; etc.  Running down to the local gas station for a loaf of bread wouldn't be covered as an example.  Read your contract to be sure.[/I]  For a minor accident you'd probably never have a problem even if you were outside the limits of the restrictions but in a situation where there was a major liability involved you could be denied coverage if you were outside of the usage restrictions.  You could stand to lose a house, savings, etc. resulting from a law suit in a situation like that.  It's just not worth the risk IMO.

Rob, Here is a compact 1" master. 90-96 Acura Integra LS. Looks like you could use the Wilwood remote reservoir but outlets are on the right side.

I've been scanning a bunch of them -- haven't found a site that lets you search for things like bore or flange "orientation" but PartsBin.com at least has pics & lists the bore.

Do most of the ones w/single reservoirs have a divider?  I'm guessing so because if not, would seem to defeat the point of a dual circuit master I think.

Rob, The 1" master I show above is for ABS,non-ABS is 15/16". Mid 80's Honda Accord looks the same but is 7/8". Here is how the dual master single reservoir works:

Hey Jim,

I spend a lot of my day sourcing parts and making things fit where they weren't meant to.
And I'm the go to guy around here when you get stuck.
But you make me look like a rookie.
I am endlessly amazed at the parts that you come up with.
You are the master, and have my humble respect.

Cheers
Fred

Thanks, Fred! I enjoy finding things that work and helping others.

Thanks Jim -- 15/16 will likely be ok.  Don't really know what I need or how to calculate it.  Just can tell the 3/4" MC isn't pushing enough fluid.  

My plan is to try something in this range & adjust from there.  That's one reason I'm focusing on the less expensive ones.  The one delimma I have is the ones identified so far (by you and a few I found on RockAuto) aren't stocked locally -- I'd have to order & pay just to be able to see it.  I know I need one that's no longer than 6 1/2" from face of the flange to furthest back point -- haven't found any on-line resources with measured diagrams yet.  There must be one out there though.  That way I can rule out the ones that will be too long.

Rob, I know that Acura 15/16" is short enough but I wonder if the reservoir is too tall or far back. I think it would be just right for your Wilwood front brakes but, I think you would need a proportioning valve to turn down the rear brakes a bit. I would cut the mounting ears down just below the bolt holes and drill new mounting holes to make it more compact. Those were the shortest looking ones I could find. I'll try to find a measurement for you. You could get one at the wrecking yard and if it will work,buy a kit to rebuild or use for core charge on new or remanufactured. 88-89 Accord(only 7/8 though) and 90-91 Prelude SI (15/16)look the same and dirt cheap,no core required at Rockauto.com.$30-$50. Picture of Prelude:

Here is another compact master cylinder(7/8").1999 Honda Civic EX. Looks like you could turn reservoir around for backward facing early MGB.

Thanks Jim.  I like the reservoir on that one... but given how soft my pedal is with 3/4", I think 15/16 or 1" is what I'm going to need.  I picked up a 15/16" one since it's in the middle of the range (7/8-1").  Going to try that & see how it works & go from there.  eBay seems to be a great way to find stuff like this to try out -- used, but cheap so if it doesn't work out it's not the end of the world.

Yeah, I just posted the other one for those who need a 7/8". In my experience with Toyota 4 piston calipers (about the same piston size as your Wilwood) 15/16" is perfect. Your rear brakes are somewhat large and probably need a proportioning valve. If you went 1", it would be perfect for the rear brakes but, a little large for the front and produce a harder pedal feel. Are you getting the Acura or the Prelude one I show? Remember to bench bleed first. Also the push rod may have to be adapted and just a little slack(1/4" freeplay at pedal). Usually the fittings are 10mmX1.0 if one looks larger it is 12MMX1.0. Use a short separate line with Metric on one side and Inverted flare on the other.Then  to 2 LB residual valves, then to your existing lines.. These masters are meant for 4 wheel discs but use a separate residual block. Good luck and keep us posted.

Thanks Jim - the one I got is the Legend LS one.  Ports are on the right and look like they'll clear the pedal box.  I already modified the ears and drilled new mounting holes.  Haven't found a reservoir yet but local bone yard says they have the prelude one & I think it'll fit.  In the mean time I've jerry-rigged a reservoir using some poly tubing and a pvc fitting for the cap.  Should work well enough to try it out.  Hope to get it swappwd in tomorrow or Weds nite.  Will keep you guys posted.

Cool! Boy, you got it fast! How long is it?

Can you post a photo of the end where the clevis goes in. Does that piece in the Photo come out and does it have a snap ring to hold a normal push rod in or did Honda use a different setup?

Quote:  "How long is it?"
 -- Measured a couple of days ago -- was shorter than stock MC -- about 5 3/4" if I recall.

Quote:  "Does that piece in the Photo come out and does it have a snap ring to hold a normal push rod in or did Honda use a different setup?"
 -- Don't know what Honda used, just have the MC.  Does have a snap ring that holds the tube extension you see in.  That tube acts like a push rod.  I haven't taken it apart yet to see whether it makes sense to try & use a regular push rod in place of the tube or maybe use a push rod inserted into the tube... will be spending some time on that this evening I hope.  Will post photos once I figure it out & set it up.

Probably just insert the pushrod in the tube. Rob is trailblazing this one. Looks very promising so far. I wonder if the Honda reservoir is forward enough (for the backward mount early pedal  box)or the Wilwood remote reservoir  can be made to fit. These masters can be found cheaper than the stock ones and availability is better also. May become the master cylinder of choice in conversions with larger brakes.

Well, push rod on this one probably doesn't matter unless there's a short reservoir.  Take a look @ the comparison...



Height of the reservoir can go about 4.25" from the side of the box where I'm measuring.  This one is almost 2" too tall too...


The hole where the reservoir connects measures 1 11/16 (it's probably a metric size but it's very close to that).  I have a Tilton 75 & the reservoirs for it have a smaller diameter hole.  Not sure what size the Wilwood MC's use.

I think I'm going to punt on this one & search around to see if I can find a version of the Honda Civic one that Jim posted earleir but in 15/16 or 1".  Seems like most of these MC's are available in a few different diameters so may get lucky.

Rob, That is what I was worried about, I have another idea. I wonder if you can look at the clutch master reservoirs on the Honda's  in the wrecking yard-they are remote and maybe the part that fits on the clutch master will fit on the brake master. Scratch the clutch master idea, I saw a picture and it uses a small threaded fitting. That gives me another idea- how about threading the part the reservoir goes on with pipe thread and using a reducer bushing with a small nipple to run hose to remote reservoir.
