No brakes

Post by Jimj »

Evening all.
Need some help on how to improve the brakes on a 1996 Toyota DC 4X4. I've put in a Lexus V8. Absolute monster. But it takes along time to stop.
Do I change the brake pad quality?
Do I change the booster to a double diaphragm?
Is there a mod to the brake cylinder or change to a different one?
Can I change the calipers to bigger ones with bigger pads on the front? Are there calipers that are interchangeable between models?
What can I do to the back drums?

A big safety issue and the problem is compounded by having the extra power / speed. Additionally, if you have bigger diameter tyres / wheels fitted, the braking power is reduced since the wheels have more leverage against the brakes.

You can try PowerBrake. (They have centres up your way). From what I have heard the change the discs and fit their brake pads - not too cheap but makes a marked difference and some guys will swear by them.

Otherwise you can fit Cruiser 75 discs and calipers - straight fit, but more pricey than the PowerBrake option, yet apparently more effective. You can further improve braking by fitting a bigger master cylinder and / or upgrading the booster.

Most of the braking power comes from the front wheels but having the rear ones working optimally is just as important. Much of the above will affect only the front brakes, so after you got the front sorted it is equally important to set up the rear. There's not much you can do with the drums & slave cylinders themselves other than firstly making sure they are in good order and working. Then (a factor that is very often overlooked) you have to set up the LSPV since it will have been adjusted for the originally weaker front brakes. Adjust it incrementally until the rear wheels start locking under braking with no load and then slack off the adjustment fractionally so that there is no more rear wheel lock up.

Good luck and let us know how it goes. :winkx:

Andy you must use the Cruiser 75 ventlitated dics with KZ-TE calipers and not the Cruiser 75 calipors

Will the Cruiser 75 ventilated discs and KZ-TE callipers work on a IFS petrol Hilux too? Sounds like an good option. Also considering a Powerbrake setup.

Thanks Guys

If Powerbrakes still stock the SFA kit, it is a worthwhile investment. They make a huge difference! One of the best mods I have fitted to Bulldog.

Compare the costs of the different options i.e. replacing the calipers, disks and pads vs the powerbrake option. You do not even need to get the powerbrake disks as the only benefit they provide is the slots in the discs which work away mud to ensure braking even in muddy conditions and have wear indicator slots milled into the disks.

I would get the brake pads they sell first and see how it goes.
