i have a 98 5sp S/C base model.. car has no abs i was thinking about getting WW bbk but my concerns right now is should i spend 600 bucks for bigger calipers and rotors? 60mph+ when you want to stop the wheels just locks. car just slides like if im in a frozen road. i know to solve this i need a complete abs system.. will a BBK help without getting ABS system? thanks in advice

wtf is a "s/c" model max?

and no you don't need abs for a bbk..

I ment 98 5sp supercharged SE base model no abs. And I know I don't need abs to put bbks my question was will the bbk help stopping fast without locking the wheel?

No if you're locking the front wheels now, more brake won't help that. You need to look at your front tires first. You are going to have to learn threshold braking.

+1.

Get wider/heavier tires, that would also help with traction loss when accelerating.

Yes bigger brakes do help with stopping, but it seems to me that you have a bigger problem. If you sliding like you're on ice at 60+ then you need work on your braking techniques, slow down or do so good ole down shifting to help with stopping. A good Z rated softer tire would help a little & a wider tire would help, but its not like you can that much wider than what you already have, to even make a noticeable difference

Accelerating??? Hell, his problem is with stopping

larger brakes will make you more likely to lock up the wheels, not less.

I just posted this in another thread...but I like evangelizing against big brakes.

Big brakes will only make your problem worse. Your problem is your tires. Get new tires.

A tire can supply only so much force in any direction - google "traction circle" to learn more. The includes backwards, i.e. stopping the car. If you're locking up right now, it means that when you hit the brakes, you're exceeding the amount of force your tires can provide. If you get bigger brakes, you'll be able to apply more force to your brake rotor and thus more stopping torque to your wheel - which means more force will be required at the tire's contact patch to actually use that to slow the car. If the traction to supply that force isn't available - and since you're already locking your tires, it isn't - you just can't use all the extra braking power.

What you need is tires with a better tread compound, or that aren't bald as *****. I realize that saying "I got new tires" doesn't sound as sexy as "I upgraded to a bigger brake system," but it sounds like your concern is really with safety and not appearance (as it should be, if you're locking up at 60). If you get new tires with better grip, you will spend less than $600 and stop sooner. If you get bigger brakes, your wheels will lock more easily and you will be just as boned.

+1 ^^^ great explanation

+2. I love explanations like that.

He said: it will ALSO help with accelerating. If his tires don't let him brake so easily, they probably won't let him accelerate easily.

You can lock up tires @ 60mph?

I may need a brake job then... Or you need to learn human abs, my money is on you forgetting to clutch in.... So you stall the engine which is locking up your tires.

you are less likely to lock up your tires if you don't press in the clutch, not more likely.

Hrmm, just my assumption from my close call a month ago, I was running under that assumption until then....

A car decides to pull out in front of me (had 2 other lanes to choose from, had to choose the middle lane, me) on a road where the PSL is 50mph. I had to slam on my brakes thinking that i should stay in gear, started braking really hard, the tires locked up, then the engine stalled causing my fronts to stay locked up, which I then quickly clutched in, then resume the human ABS procedure, I was within a foot of that idiots bumper.

After that day, I just ran with my assumption, there could have been an alternative explanation which made that close call so close, but that's my most logical assumption above.

alright i bought the car as is car were sitting on previous owner yard for over a year. all 4 tires are brand new tripple A traction not even a month used. car had SS LINES all around but somehow one of the lines wasnt working properly i changed my calipers and i notice theres was not enough fluid going to the caliper. car was locking cause only one side was braking went back to stock all 4 lines are nissan now.. and no car did stall on me cause left tire was still spinning while the right side was locked.. everything is fixed now car stops fine but it takes a while to stop from 60 to 0.. but im get 6th gen BBKs to help... i never had this problem on my 5th gen... thanks for all the explanation guys...

I did a 0-100-0 pull the other night, it was pretty sad. I was just getting some data to play with my Performance Box before a track event. My Maxima is a non-abs model, so max attack braking is a challenge. I could only pull -.8G before the fronts locked up, I'm going to try again with different tires on the front. That pull did freak my TCM out and cause the trans to go into limp mode. I guess it did not like me locking and unlocking the front wheels from 100-0.

looks like this, you can see the how much braking Gs are lost when the wheels lock
