I have a lwb 1.6 vitara and I need to upgrade the brakes
I have sloted and vented front rotors
Is there any master and boosters that have a higher pressure that will bolt in with out to much trouble
Will rear disk help much
I'm looking to see if I can get a gvm upgrade so i want the most stopping power that I can get

Fit 2.0L rotors and calipers. You'll need 16 or 17" wheels though.

Do you have the same Isuzu rodeo's and Isuzu trooper's we have, over there?

If you do , let me know and I will find the thread that documents the M/C booster swap, it is bolt on and helps heaps.

Yes, we do, but they're called Holden Rodeos (or the new Colorado) or Holden Jackaroos. Of course, they are also RHD, so there may be a difference with the size/layot of the Booster and Master Cylinder.

Look into heir booster and M/C Weed over on Zuwharrie bolted one right in place he did a nice write up on it.. I believe the lines/fittings are metric as well.

I've got standard front with BenT's Rear disc kit. It's gooood. Made a massive difference. The only downside is that I didn't get slotted rotors, which I kinda wish I got now.

For the price of new drums and shoes, you may as well get the rear disc conversion.

I want to see how much the mc and booster do before I go to bigger front brakes as it would mean buying 8 new rims and tires

[Brett]

Are the gv brakes bolt up except the needong bigger rims?

[royce]

doesnt matter how much you change what creates the pressure into teh pistons, a given caliper / rotor combo will only provide so much braking effort, I dont think there is any requirement to be able to provide a given amount of braking for a certain amount of pedal pressure

[Brett]

So is it a bolt in or are the master cylinders different?

One of my mates has just done the Rear disc brake combo upgrade, omfg... its like having a set of twin spot's compared to mine

Why do people think discs offer more outright braking power?

[stocker]

we did a test. side by side, same time ( i cheated a little ) and he still pulled up before me... ...Question not a statement, but aren't Disc brakes more efficient at dissipating heat, therefore providing better stopping power ( like i said royce question not a statement, thats just what i was led to believe and whether that was the blind leading the blind i don't know)

[royce]

Discs are better at
being simple to build and install
being virtually maintenece free
working when wet
dissapating heat

So all that makes them more reliable in a passenger car, the heat thing is more of an advantage during repated stops rather than single outright

They have a lot less friction area than drums so need to squeeze a lot harder than drums for the same force, when you jsut bolt discs on the back you still have the same input pressure

Anyone who has driven 4 wheel drum brake cars a lot will tell you they pull up well, when they are sdjusted properly and are cool , which is pretty easy in the back of a Suzuki

[stocker]

i see... well i do have well adjusted drum brakes (till it locks up and 3 clicks back ) , new shoes, and i've got brand new cylinders... and mine doesn't pull up as well as the other LWB with disc's? Please explain??? i really wanna know why that is.

[royce]

most of the braking goes on in the front, same pads and rotors? same tyres? same suspension? same tyre pressure? same shock wear?

[stocker]

well i have all brand new Dobinson Shocks same size tyres, different type.

He has same suspension except still calmini struts. same BL, Same tyre pressure.

I have RDA Slotted Rotors and Bendix 4wd Pads, he has RDA Solid Rotors and Bendix 4wd Pads...

Spring lift can alter how the rear brake bias sensor works.
Adjusting that, or compensating for the height increase,
can make a huge difference to brake performance

[flatcat_auz]

My 04 GV is running slotted rotors and braided brake lines and the difference is awesome.......cost me a fortune but well worth it

[cooo]

you can still get away with 15" rims with a very slight bit of grindage, im running 15X7 sunnies on mine with 0 offset

[zuk94]

Slotted discs would be a pain to clean if off roading all the time especially if you like mud etc. . Wouldn't they also in those conditions collect stones and gravel in the slotts and wear grooves in you pads . Be good to know from someone whose tried them out.
