Have you tried to bleed the brakes,it sounds like you have air in the system. I would try bleeding the brakes first ,start with the wheel farthest from the master cyl. The right rear,left rear,right front left front. If that does'nt help check the master cyl and brake booster.

My brake lights don't work and turn signals but


ABOVE THE STEERING COLUMN there is a 6way plug it's hard to see but it is actually a jumper from brake switch to main instrument panel, check to see if this is plugged in and fully seated, you will have to get a big screwdriver and pry this plug loose it has a rosebud holding it in place from factory. I used to see these quite common at G.M. Factory where I worked. I recently chased one of these down for a guy and it was this way from factory and finally worked its way loose. If you check this out and it is'nt the problem then it is probably your turn signal switch in the steering column, because the brake,turn and Hazards all run through there. I take it that you already checked out your tailight circuit boards when you checked out the bulbs.

Brake Lights all of a sudden not working on my 1995 Tahoe. Checked fuses and lights. Neither burnt out.


The turn signal switch and the hazard switch are likly places to look. To checjk the fuses is'nt to take them out and look at them but to test to see if power will go though them, I use a test light ( a tool that looks like an ice pick with a wire coming out of the handle and the handle is clear with a light bulb inside). with the clip connected to a good ground as you touch the back sides of the fuses the light will light if it only lights on one side, the fuse is blown ( does'nt matter what it looks like ) a bad fuse can look good. the turn signal switch is involved as is the Hazard switch. If you pusth the hazard switch and the lights light good then you know that the lights and the sockets are good. You also know that the wires are good . With the key on the turn signals should work front and back ( thier different cicruits) If only working in the front the turn signal switch is bad provided the hazards worked all the way around. Does the high mount stop light work? It works off of it's own circuit on the brake light switch and if no lights work your back to the fuses only after you checked to see if the high mount bulbs are good. Your car is plenty old enough to have them be burnt out. If the high mount doesn't work with the bulbs known to be good and then you check with the test light to see if the power isd getting to the brake light switch. One wire is hot with the key off and another comes hot with the key on ( the cruze control switch in the brake light).

Brake lights dont work Bulbs are good and brake light switch is good


The power flow for the brake lights goes like this: Fuse ->Brake switch -> Turn signal switch -> Rear lights. The only difference is, if you have a 3rd brake light in your rear window, that gets its power directly from the brake switch. It does not go thru the signal switch first. So, if you are having a brake light problem, and your fuses are good, check the 3rd light in the rear window, if it lights up (assuming the bulbs are good, no one ever changes them), then the problem is most likely in the turn signal switch, hope this helps!

My antilock brakes are sort of working once in awhile when I come to a stop. It is Summer and they should'nt be doing that.


anti lock brakes work at anytime. that is the purpose of them
If you are claiming they are locking up or pulsating you have a mechanical brake problem from wear on the pads and rotors

I have a 1990 911 Porsche Carerra 2 convertible. I can't seem to get the top to go back up. Not sure why. The car has the key in the accessory position with my foot on brake and parking brake enabled.


You can always close the top by pulling it up by hand. It pulls hard but you can pull it up and it might require two peaple, and then latch it down. Fuses fail to connect in the fuse panel and the switchs fail as do the motor in the pump that makes the top move. Your right also that if the car doesn't sense that the e= brake isn't on or the is'nt moving it'll not work the top either. Many fuses have to be good for all the systems that interlock the top to work the most common fuse to blow is the cigar lighter fuse as peaple plug in things that short out oftern.

How to release tension on parking brake cable to remove from rear caliper - 2008 Ford Taurus X


you should'nt have any tension on the parking brake,unless it's on. check the parking brake to insure that it's in the off position. chock" the rear wheels,to make sure the car does'nt roll while you're jacking it up and "always use jackstands,do not trust your jack" does your brake caliper piston have a + on it?it will be on the brake caliper piston itself, if so,then you need to back the brake caliper piston back in by turning it counterclockwise,auto parts stores sell a special tool to back the brake calipers back into place, i've always used a straight screwdriver,to turn the piston counterclockwise some do turn clockwise though to retract the brake piston. a simple call to the auto parts store where you're purchasing the brakes will tell you which way the piston will need to be retracted.other wise,it's a simple brake replacement,just push the brake caliper cylinder with a "C" clamp to retract the brake caliper, also,if you are replacing brake rotors,purchase the brake kleen to spray on the new brake rotors when you replace those.they have a clear film on them,you'll need to remove that film to insure no future issues with the brake rotors.simply spray the front and back of the brake rotors with this spray to remove the protective "film"and as always,thank you,for choosing fixya.com!

2004 dodge dakota. brake lights not working but bulb is good. taillights and turn signals are working. Is there a mechanical switch by the brake pedal to look for??


there is a switch above the brake pedal that turns the brake lights on when u depress the pedal, use a volt meter set to DC volts and check for voltage to the switch and out of it when the brake pedal is depressed, see p[icture of switch belowe364f34.jpg
