tires screeching

hello recently got a new to me 1999 tacoma pre runner 3.4L and getting used to how she handles.
as far as condition goes for 187k miles its practically new, new tires on me as well.
however sometimes when Im breaking from say 30 or 40 to 0 my tires loose traction and wouldn't say im breaking too hard should I juts be driving slower and easier or is there an issue.
I wouldn't want to end up on the highway losing traction at 60-80 mph.

 

So, yeah. What is the pressure and how deep is the tread. What make and model. Basic stuff.
Observe, measure, report back.

 

I would suggest in consideration of road safety and overall cost that there is really only one answer here.

Take this truck to your nearest tire store ASAP and have the brakes repaired.

Please and thank you.

 

Does your truck have ABS? Is that ABS system in working order?

 

Is it your brakes locking up?

 

No its just the tires id describe it feeling like my truck is too heavy I suppose and once their stopped i keep sliding

 

ABS is fine emergency break is fine I even had my breaks blead

 

tires are new all season all at 30psi 1999 Tacoma 2WD 3.4L 6cyl

 

inspect rear brake shoes. Sounds like you are locking the rear tires.

 

Is it only the rear wheels locking up?

These trucks had a brake proportioning valve on the rear axle. As payload increases in the bed and it is weighed down, it pushes on a lever that increases rear brake pressure so the front brakes aren't doing all the work. If that valve or lever mechanism is not functioning and stuck in the down/ loaded position, the could be the issue.

I've highlighted the bracket and lever on the rear axle, which has a long connecting rod up to the brake proportioning valve near the upper left frame rail. The valve body itself may be faulty, or the rod may not be connected or may be bent/damaged.

what did u drive B4 the Taco?

 

2004 Toyota Corolla still my daily at 134k but comparing the breaks I practically go to the floor on the tacoma where as the corolla starts slowing down with the slightest pressure

 

understood^^^^

if goes to almost goes to floor....

what is the level of fluid on your brake MC?
if lower than 1/2 way full,
i would pull off front wheel and check brake pad thickness
do the same to the rear wheel and check shoe thickness

 

Ah, this looks like component failure in the taco somewhere.

 

On the sidewall of your tires look for raised lettering that says DOT. To the right of it there will be 4 numbers. The first 2 are the week the tires were manufactured and the second is the year of manufacture. Tires have a best is used by date. Tell us what you find.

Check fluid level and adjust rear brakes. Tires have no effect on your pedal going to the floor

 

I re-state my advice above. Take the truck to a professional Tire, Brake, Alignment type of shop.

* Tires are not your problem. They are new and properly inflated. So eliminate them from your thought process.

* It is quite possible you are still getting used to the difference in overall braking performance between a small car and a mid-sized truck. Your truck is older, heavier, and has higher mileage than the car you were driving.

* My biggest concern is that your description of the issue doesn't quite make sense.

--> As above, tires are not your problem
--> As above, yes your truck is heavier than your car. However, what do you mean by too heavy? Is there armor, a camper shell, an over-sized lift kit or something else going on?
--> It is not possible for you to keep sliding once you are stopped. What does this mean? I suspect you meant to say that even with the brake pedal fully depressed, you are still braking poorly (slowly). Not skidding, not sliding, but still moving forward.

Note: ABS was optional in 1999.

Note: It should be very easy to determine if your rear brakes are indeed locking up. As others have suggested. Get a friend and go someplace safe and have him / her observe from a safe distance as you come to a hard stop.

Note: Just because you had your brakes bled, does not mean it was done correctly. Especially if a friend or family member did it. This takes experience, the correct tools, and following some essential principles.

Bottom line is this:
That your brake pedal is going to the floor is a very strong indication of air in your brake lines or leaking brake fluid somewhere.

You bought a 25 year old truck with 187,000 miles on it. There could also be some other tricky problem you are experiencing. Just as likely, you could simply have brakes that are completely worn out.

Any good shop will have your issue diagnosed in 1 hr. Maximum. Complete inspection. Because the braking system is very very simple. And they will have seen and serviced dozens and dozens if not hundreds of trucks like yours.

Get your truck to a shop.

 

The tires COULD be the problem. What is the date code? Just because they are new to you doesn't mean they haven't been sitting in a warehouse for 6-7 years. It happens especially with less common sizes. Rubber deteriorates over time and gets hard. New soft rubber tires grip better.

Manufacturers can make tires of harder rubber and they last longer but traction can be poor, especially on wet pavement It's been years ago but I got a set like that once. Brand new and they were dangerous on wet pavement. I kept them a year, about 8000 miles, but replaced them ASAP.
