Does the Vit boosters bolt up to Sierras, and if so are they more powerful? Ive fitted suby master cylinder, LWB vit calipers on front, and 323 calipers on rear. It stops great, but only if you put a lot of welly on the brake pedal. I want em to feel a lot better than that, and i suspect its because there isnt enough vac assist.

Sierra's are light vehicles and their brakes are pretty good in standard form, for the recreational 4x4ing that most of us do you are not going to get a lot of benifit from brake upgrades, brake fade and overheating are usually not an issue when crawling around the scub. It is just not as simple as bolting on different parts from different cars, unless you have the technical knowhow to do it properly forget it. My sons workshop has an electronic decelerometer that does a printout of the a vehicles braking efficiency, some cars that feel like they pull up great are actually less efficient than other that don't feel as good. For example to me some of the ABS cars I drive do not feel like they are as efficient as some non ABS cars but the efficiency reading is different to the drivers seat feel. Because some cars grab well the brakes feel really good but under testing they may actually lock up way too early before they can knock off enough road speed and therefore they loose traction and loose efficiency. My advice is ask yourself why you need better brakes, it may be that your standard braking system is just buggered and needs to be overhauled. I would be carefull that your search for better brakes doesn't brings you unstuck as it has with many people in the past.

I am going to upgrade due to the intire systme needs to be overhauled anyway. When slamming on the brakes it pull to the right. My front pads are very uneven. both my rear cylinders are leaking so instead of spending the money to rebuild I am going to upgrade. I do a lot of mud and water wheeling that is my reason for wanting disc's in the rear. With disc's in the rear to keep it in good front to rear perportion I am going to upgrade to a bigger set up in the front.

Mud reliability is a huge win for discs.

Also, you can't loose a wheel if a bearing collapses - the caliper holds it on.

do the v6 discs fit?

has any one ever had a look at a f100 brakes?
