Title: brake booster chev toploader install Post by: simins on June 13, 2006, 08:30:08 AM i am looking for suitable brake booster setup for my FC
i am running 350 chev,dellow bellhousing,toploader gearbox. i would prefer to use hydraulic clutch setup i am possibly considering hk,t,g booster master cylinder or datsun 180b booster and mount with ford xb cylinder. car has four wheel discs. any thougts would be appreciated simins Title: Re: brake booster chev toploader install Post by: Russ on June 16, 2006, 03:04:33 AM Hey Simins
My fc has a seperate booster mounted on the inner gaurd i thought that was original, if it isn't i'll find out what it's off and tell you, but it works fine in mine. (only a six though) PS did you put the V8 in yourself? Russ Title: Re: brake booster chev toploader install Post by: mcl1959 on June 16, 2006, 07:19:11 AM Depends what look you are after. If you have room for the mastervac this is a much better solution than the remote booster. HK/T/G setup is OK if not a little on the large size, but has a metal m/c with metal lid.
Newer units are better such as Commodore with a plastic m/c body and lid. Late Commodore has a plastic booster as well as a fast fill m/c. Another advantage of the Commodore m/c is that it has the proportioning valve built in. All options are equally suitable for most brake upgrades as long as you choose one with 1 inch bore. The Datsun booster is a little limited in vacuum capacity and may not pass engineers, this depends on the engineer you choose.

myself using a CRS chassis kit and CRS hr front end with HQ discs and calipers . will possibly upgrade to aluminium HZ calipers the rear end is narrowed nine inch with VN axels and discs and calipers remachined to HQ stud pattern. Ken thanks for your reply i have since looked at a VT booster /master cylinder it appears the way to go although i think the clutch master cylinder will require a slight sideways relocation thanks again for both replies i hope to be at next melbourne meeting to join up Simon Title: Re: brake booster chev toploader install Post by: JB on June 19, 2006, 06:45:54 AM Simins,
I have the Hadfield front and and it is puss... Not much truning circle and scrubs inner and outer of the tyre. Not worth the money I paid. Mine is the front rack version, so the rear rack could be an improvement. The half chassis on the other hand is very good. If you were going with the Vt booster, why not stay with Vt calipers and rotors on the front. The Vn rears are also compatible for engineering purposes. Cheers jason.

my chassis kit with the front end completely rebuilt and powder coated having never been installed so it was to good to pass up. Mine is a front steer rack conversion. Am currently dont know if a rear steer rack would give sump clearance for chev. I am running the HQ stud pattern because of my wheel choice which are 7 inch pontiac firebird rims.A factory 7 inch version of HQ GTS rims. Ill have to see just how steering lock is when i hit the streets. Thanks again Simon Title: Re: brake booster chev toploader install Post by: JB on June 21, 2006, 08:22:09 AM I can't do a U turn on a standard street, and have to have a couple of go's at some street courts.
Good Luck Jason. ;D Title: Re: brake booster chev toploader install Post by: RET on June 21, 2006, 08:45:05 AM Quote I can't do a U turn on a standard street, and have to have a couple of go's at some street courts. Good Luck Jason. ;D Even with standard kingpins and big tall rag tyres that can be a bit of an ask... ;D Can you believe that the 36 1/2 turning circle was once listed as a selling feature? ::) cheers RET Title: Re: brake booster chev toploader install Post by: mcl1959 on June 21, 2006, 08:51:12 AM I believe you may have difficulty with your wheel choice.
A. HQ offset rims like the Firebird are dished much more than original FC rims. B. HQ brakes on HR stub axles will also push the wheels out 24mm per side. If you want to run a low stance the wheels will hit the mudguards. Try putting a 1 inch spacer between the wheel and the hub on an original FC front end to see where the wheels sit, especially during turning. Ken Title: Re: brake booster chev toploader install Post by: simins on June 21, 2006, 10:57:13 AM Ken i have test fitted the wheels they will run realy close
to the front guards . I have also purchased a set of adaptors from Hoppers Stoppers to run a set of Leyland P76 disc rotors,which have had the stud pattern changed to HQ pattern. Note this is for mock up purposes only. If it works succesfully a new set of blank drilled rotors to suit P76 with HQ stud pattern will be sourced through DBA. P76 rotors run approximatley 20 mm a side narrower track am yet to mock up and confirm exact measurement ,thanks for the input .This is a terrific site Simon |
