I plan on installing a DB7 Manual Pedal box/vacuum servo/master cylinder in my 1986 v12.

Seems straight forward, just a couple of short lengths of custom brake lines required.

ive been using a Jaguar Specialties converted pedal box for a few years without issue but came across a DB7 vantage setup that I wanted to try. The brake master and reservoir takes up less room. Wish me luck, haven't seen anyone try this yet, seems simple enough as the 1996 xjs used the same bits.

 

Watching with interest. Just about ready to install a manual peddle box in my ‘88.

Also interested to see how that works out 🤔

 

Also watching with interest. Do you have a part number for the DB7 pedal box?

 

See here for part numbers:
DB7 Vantage (1999) Pedal Gear, Manual Brake & Clutch (5.5B)

Providing it fits(which I expect it to), my current set up is in the “for sale” section.

 

Should work.

 

Where did you find this set up? And when do you think the swap will be finished?

 

parts came from ebay. I will install as soon as they are delivered. By end of the month probably.

 

It fits.

also, pedal box seal and rubber pedal pads are still available from Aston Martin, and under 10 bucks each. These appear NLA from Jaguar.

 

Looks like it belongs in there. I was watching a DB7 on BAT the other day. I will own a manual V12 car at some point.

 

Is there any reason a RHS version of this reservoir would not fit on a standard Jaguar V12 m/c, thus doing away with the remote reservoir?

 

Greg,

All these brake parts are originally Jaguar. Aston used the Jaguar setup as they did with front subframes etc. Anecdotally, I heard that they didn't want to have an ongoing dependency on Jaguar, so stocks were produced at the outset to cover production and ongoing parts for the DB7. Hence why you can still get some "Aston" parts even through Jaguar ones are NLA.

So the RHD Aston parts fit UK Jaguars. Do you mean, if the late Teves IV-type reservoir will fit a pre-ABS XJ-S Master Cylinder, or a Teves II Actuator Unit? The issue might be how the fluid feed works from the original reservoir on a Teves II system to the accumulator pump?

Thanks for the skinny. I was wondering if that triangular reservoir (I did not know it was from a Teves system) would actually fit onto a pre ABS master cylinder, not foulf the bracing strut, and allow the bonnet to close. If it would, it would greatly simplify that corner of the bonnet!

 

The triangular reservoir was one of the reasons this swap appealed to me.

the MC is totally different from what was originally on my 1986, the reservoir will not fit the earlier style.

this one does not extend beyond the brace as the original does. It will
also require custom bent lines to connect from MC to the connections to the main lines.

 

although nothing wrong with the E Type pedal pads I had with the old setup, these don’t give away the swap as easily.

 

Well done! Now I just have to find the parts. Been watching eBay but nothing yet.

 

By any chance would the master cylinder assembly bolt to the existing jag booster?

 

no, the booster and the master are matched. Need both. 3 bolt on this one vs 4 bolts on the one i replaced.

1995/1996 xjs and some years XK8 used the same master and booster though, probably easier to find if piecing together separately. You would need the triangular reservoir though, that can be bought separately. Best bet is to find an entire assembly like I did. Check ebay, ther ris a seller that has a lot of DB7 parts
