Mitchfromhillcrest Posted November 26, 2015 Share Posted November 26, 2015 Looking into possible brake servo relocation as mine has a great big ugly linkage system in the bay. And want to make this. Mounted under my dash. Question is though, the legality of having the booster,master cylinder and lines starting inside the car? I want to keep boosted brakes and want to keep somewhat OEM parts (m/c booster etc) mainly for maintenance. Shoot the idea down or shove me in the right direction. I can make all the linkages at work so no stress on fab work. Chhhhhhheeeeeeerrrrssss 1 Quote Link to comment Share on other sites More sharing options...
KKtrips Posted November 26, 2015 Share Posted November 26, 2015 You'll probably need tech approval for that but I've seen inboard brake lines etc. before. For simplicity sake because you'll need a lot more of room for all that then can you delete the booster and run bigger master or more leverage? Or run a remote booster?

Yowzer Posted November 26, 2015 Share Posted November 26, 2015 Perfectly fine to mount under the dash, however there are some strict rules on the construction regarding materials, welding, fastening etc etc. As well as the linkages. As KK said, you'd want to talk to your certifier and send your proposed design for tech approval before you begin, so as not to waste all your time building a sweet decoration.

Ghostchips Posted November 26, 2015 Share Posted November 26, 2015 My sisters friend put the whole brake and booster under the dash and it's legal, i can try and find out more about it. Quote Link to comment Share on other sites More sharing options...
Frosty Posted November 27, 2015 Share Posted November 27, 2015 It's factory on a lot of forward control vans for a booster and master under the dash and may be adaptable making compliance a bit easier. The Lite Aces even have the clutch master under there to, fells a bit odd pulling the cluster out to fix them but it works. Brake, fuel and cooling lines in the cabin are also allowed which can make a smooth under belly feasible on an older car. 1 Quote Link to comment Share on other sites More sharing options...
Mitchfromhillcrest Posted November 27, 2015 Author Share Posted November 27, 2015 One reason to keep the boosted brakes is that it'll be a daily and my partner will need boosted as she's week as f .I was going to attempt to find something stock from another Vehicle and either rebuild or copy it. Since I'm young and own vws, I'm not liked among the cert guys in Hamilton lol. But will draw something up and at least get it looked at first. Will be researching "remote ones" which I have never seen so To google I go. Cheers boys 1 Quote Link to comment Share on other sites More sharing options...
Frosty Posted November 28, 2015 Share Posted November 28, 2015 Stupid question. Would it be possible to move the linkage to inboard and leave the master and booster where it is? Another option may be a cable. This would still use the stock master and booster in the normal position and making parts easier in the future. It may still require a cert but I doubt anyone would notice. Quote Link to comment Share on other sites More sharing options...

Personally i would look at after market race typed products as the are usually easy to retrofit Quote Link to comment Share on other sites More sharing options...
Yowzer Posted November 28, 2015 Share Posted November 28, 2015 Keep in mind the rules for custom brake systems are very strict. Here's a thing with some info http://www.lvvta.org.nz/documents/standards/LVVTA_STD_Braking_Systems.pdf Relevant info on pages 8-9 Quote Link to comment Share on other sites More sharing options...
Nominal Posted November 28, 2015 Share Posted November 28, 2015 Yeah, I don't think a cable is going to be acceptable in a hydraulic braking system mechanism. Quote Link to comment Share on other sites More sharing options...

For simplicity sake because you'll need a lot more of room for all that then can you delete the booster and run bigger master or more leverage? Or run a remote booster? A larger master cylinder would produce less pressure and require even more pedal effort, (the relationship between bore size and hydraulic pressure is an inverse one). With the Mk 1 running a dual m/cyl you would need to run two hydrovacs (remote boosters) and it would be a big step backwards in pedal feel. I like the idea of using an under the dash mastervac/master cylinder setup from a forward control van, the Hiace springs to mind? Quote Link to comment Share on other sites More sharing options...
Mitchfromhillcrest Posted November 28, 2015 Author Share Posted November 28, 2015 I do know they are fussy as f. Hence why something from a Hiace or similar maybe used. Still researching though. Relocating the whole assembly in to the inside might be do able? The original linkage pushes forward but if i could somehow spin it around i may be able to mount the booster reversed or at 90 degrees.

fletch Posted November 28, 2015 Share Posted November 28, 2015 http://www.kugelkomponents.com/zencart/index.php?main_page=index&cPath=4_5 These guys make it. You could check out all their products and make your own. Don't those e30 bmw's have a rod under the dash from the pedals on the right to the brake master on the left? One of my mates took off the 90deg part on the left side and put a charade booster onto the stock bmw master and had the rod pushing straight into it. Passed a cert and has been on the road about 9 years Quote Link to comment Share on other sites More sharing options...

ELEVNS Posted December 2, 2015 Share Posted December 2, 2015 Just a quick question in regards to this; Would it then be legal to run brake lines from the engine bay, through the firewall (with proper bulkhead fittings) and out to their respective wheel wells ie: brake line tuck? Have heard differing opinions, like I would have to run them inside covers/piping but haven't seen anything about it. Quote Link to comment Share on other sites More sharing options...

I've had cars certified with both brake and fuel lines running through the passenger compartment. Quote Link to comment Share on other sites More sharing options...
