Need help!! Want to keep 14 inch wheels... Would like to keep standard ga struts.. Any combos that would work well without booster?? ( not a lot of room ) and do sigmas and galant share same stub diameter? Any direction or help would be awesome!! Really looking for a bolt on setup, discs calipers master etc... Engineering the car, so basic guide is an equivalent to a vr4.

Try gd struts.. Still the same struts and same brakes as a ge/gh siggy just run no booster and you're set!

You don't even need to change struts - just bolt GC/GD disc & caliper onto GA/GB strut. Could probably even get away without changing master cylinder. Stub axle is the same.

There's nothing wrong with the GA/GB disc brakes anyway .... if they are well maintained & have good pads in them. Only advantage of putting the later brakes on it slightly more pad area (vs. a slightly small diameter disc on the GC/GD/GE etc compared to the GA/GB)

Is your engineer going to pass it without a booster.


Cheers Mic

Why not ? The GA & GB Galants were unboosted ex-factory, and adding a booster doesn't having any impact on braking (it just reduces pedal pressure)

Engineers are funny people, I can't see why a booster needed. And I agree that ga gb discs ain't bad either... But I need to prepare a list of proposed mods for engineer, so a larger disc and decent caliper combo is wanted.. Read on here about magna discs Volvo calipers bit from this that the other! I want to basically pull ga disc of, put another on make a calipers mount and that's it lol!

Hi, I also have a GA galant but currently with drums all round. I'm considering options for front disks rather than getting new shoes/machined drums etc. Are you sure you can just bolt GC/GD disk and caliper onto GA/GB strut? Or is that only applicable if the GA has disks already? I just got new springs/ball joints/tie rods etc on the current setup I have so I'd rather not replace everything again... But I do like the idea of disks rather than drums! Thanks, Andrew

No idea ...... I have never looked at a GA/GB drum brake front end.

Drum and disc struts th same on ga gb, disc setup has an adapter, that bolts to same place as a drum...
Im still trying to figure this out, had mentions of magna db221 disc, and volvo caliper...any one done this?

brake fade test for engineers is as follows.. 100-0 cold brake test... then 60-0, 15 times and 100 - 0, 2 times( brake fade testing)

Really want to keep standard struts, and 14inch rims... magna disc is 24mm thick vented, thatd be nice! Though I dont know if itll fit? Has anyone got a spare ga gb disc hub? Ive got a strut, just so I can suss out fitment without strippin car down...

what model
volvo calipers are we talking about

these volvo 240 calipers have 17mm rotor space apparently http://cgi.ebay.com.au/ws/eBayISAPI.dll ... 0893932403 but i think they also come in a bigger size anyone have any idea if this is right

the calipers in the ebay pic are the same ones that I have here mate that ur interested in, that I was ment to fingd and send you pics have been flat out sorry will get on to that

No worries mate I've just been researching finding out ad much info as possible

I'm pretty sure yours must be the bigger type and take a thicker rotor the ones in that eBay add only take 17mm thick if you could double check that it would be awesome, this looks like a pretty simple conversion

I think Cheaterparts still runs 13" rims on his Sigma - maybe ask him what his brakes are.....

What rotors are people using now on GB's? ... All my brake suppliers are telling me they are NLA

Im turning mine into a Rally car, so I'll be doing a big upgrade, may as well do it now when I cant get new front rotors

GA/GB rotors are still available new on eBay, but are pricey.

GC/GC/GE/LA/LB rotors are easy to get & cheaper. Just have to use GC/GD calipers with them as well, but disc & caliper are a bolt-up fit on a GA/GB strut

this is what im playing with atm $150 for both calipers delivered and $30 for the rotor, so not too expensive to see if this will work, will definitely need a bracket though

there are a few issues that can be plainly seen, may even need to look into a different rotor, one a little deeper hat hieght any suggestions

That picture has inspired me to go Alcons on the front
