hard braking

Stang187 · February 2nd, 2008, 09:33 PM

i cant exactly figure it out, ive even asked a few mechanics and they arent even sure. but braking is a pita. I cant ease on the brake pedal I have to use force, it screecthes constantly & loud when braking slowing down to 0-15 mph to a complete stop from any speed. any ideas?

bleed your breaks man, or add fluid, or your calipers are bad. Im going with bleed your breaks.

and every mechanic who said they didnt know what it could be
1. smack them in the face with a fish
2. never go back to them

Stang187 · February 2nd, 2008, 10:11 PM

and when goin down the highway or almost any where sometimes theres this squeking noise when goin straight but if you slightly jerk/turn the wheel barely it goes away but right when you turn it back straight it starts again. i gotta be goin about 50 or more mph. this is only every so often not an everyday issue.

ok now Im thinking seized caliper

ROUSHME661 · February 2nd, 2008, 10:24 PM

is the noise coming from the front or back??

ive noticed a lot of mustangs have bad paddenger side caliper i replaced both my rear ones but i know a few people and its usually the rear passenger one ...

Stang187 · February 2nd, 2008, 10:30 PM

i am pretty sure the noise is coming from the front brakes cuz dont the front brakes do most of the braking any ways?

Stang187 · February 2nd, 2008, 10:32 PM

though i culd be wrong bcuz im inside the car and not outside

ROUSHME661 · February 2nd, 2008, 10:36 PM

yeah it is kinda hard to tell sometimes but try to pay attention to narrow down wether its the front or back

Stang187 · February 2nd, 2008, 10:41 PM

is there any to see by looking at calipers?

djh1286 · February 3rd, 2008, 01:05 AM

if it was the caliper it would either be pullin to one side or makin crazy noise right?

motorhead6776 · February 3rd, 2008, 01:18 AM

depends if its just 1 side or both. and if the caliper(s) is compleatly seized or just beginning to seize so it just gets stuck occasionally. if it is a seized caliper couldnt you check the pads for abnormal wear and or excessive wear compared to the other side?

El_Cangri · February 3rd, 2008, 01:59 AM

check the fluids calipers and pads..

hookedlx · February 3rd, 2008, 01:32 PM

now are they grinding or squealing?theres a difference and what do you mean when you said you have to press hard the pedal.if you have to pressed very hard make sure the brake bostter is working properly

1. Brakes need bleeding
2. You have a seized caliper(s)
3. You have a bad proportioning valve
4. Your pads are toast, and are now chewing the shit out of your rotors because it's metal on metal.
5. Your power brake booster took a shit.
6. You possibly have more than one of the above problems combined.

hmm..

something is rubbing.

It may not be your brakes.

Also a good point and entirely possible. However I would think he still has a brake issue based on him having to lean on teh pedal, and on the noise that occurs under braking.

Possiblay two problems happening here.

I dont know if this will help u but I had same symptoms and my calipers were free so I just did rear pads and rotor. The key is get good ones. i had to chuck these really cheap rotors for good ones and wala the noise hasn't been heard since.

It is definitely not normal to have to shove your foot through the floor with a properly working power booster and master cylinder.
