The light came on because the master cylinder is low or empty on brake fluid. As for the drip, the brake line is leaking and needs to be replaced, then you have to bleed the brake system of all air.

I believe your brake line going to the back has rusted out so that is were your brake fluid is going .Have your line replaced and the truck power bleed .This is dangerous i would have it towed to a shop .

My brake lights are not working all the time on my 2000 lumina I replaced light bulbs and brake light switch and still not working just every once in awhile. What can I do??


On most models the brake light circuit runs thru the turn signal switch. The third brake light does not. So it could be a problem with the turn signal switch.
A ground problem would also affect the parking lights.

Underneath my tahoe on driver side is a small leak,clear fluid what can it be ?


Maybe brake fluid. Under the hood on the drivers side is the brake fluid reservoir and the brake lines generally run from there, under the drivers side, to the rear brakes. The lid may be loose or a line may be leaking. Would help to have someone look under the vehicle while someone pushes the brake to see if fluid is dripping.

Where do you add transmission fluid for a 2007 chevy hhr


Chevrolet recommends that the transmission fluid be changed every 50,000 miles, but Chevy intended the transmission to be serviced only by authorized repair shops. For this reason, the HHR does not feature a transmission fluid dipstick. However, the HHR's transmission fluid can still be checked without exotic tools.

It is important to check the fluid level only after the fluid has circulated throughout the transmission by shifting through the gears. Failing to allow the fluid to circulate will result in a false fluid level reading. Turn the engine on and shift through each of the transmission's gears with the brake pedal depressed and the parking brake applied. The car should be allowed to idle in each gear position for approximately five seconds. Turn the engine off, then climb underneath the passenger's side of the vehicle. A small plug is located on the passenger's side of the transmission. Remove this plug with a wrench. Turn the engine on and observe whether any fluid drips out of the transmission plug's opening. If fluid does begin to drip from the plug opening, the transmission does not require additional fluid. Turn the engine off and install the transmission plug.

If fluid did not begin to drip out of the transmission's plug, transmission fluid must be added. Turn the engine off, then remove the black breather cap from the top of the transmission. The circular breather cap twists into the transmission. Twist the cap in a counterclockwise direction until it detaches from the transmission. Because of the lack of clearance between the breather cap's opening and the bottom of the vehicle, transmission fluid cannot be poured into the breather cap opening. Attach a fluid pump to a quart-sized container of new transmission fluid. Insert the pump's hose into the transmission through the breather cap's opening. Turn the engine on, then actuate the pump until fluid just begins to drip out of the plug's opening on the side of the transmission. Screw the breather cap onto the top of the transmission, then install the plug with a wrench.

I have a 2000 Jimmy with over 140,000 miles on it. When the vehicle is turned off and I put my foot on the brake pedal, the following happens: the interior and exterior lights come on, the dash lights come...


that's a good one! of course not for you, but have encountered a lot of them almost like that, the main thing you are facing is a problem we know as 'ELECTRICAL FEED-BACK" this is cause by a lack of proper grounded circuit. have noticed g.m. trucks and s.u.v.having this problem. the best i can do for you is for you to go after the ground eyelet connectors on the frame and on the interior. the frame eyelets are on the inside of frame rail, the interior grounds are on both sides of kick panels and around the driver and passenger seat mounting bolts you will have to pull the carpet back to get to them, take each bolt off and clean. re-install with a little bit of WD-40 sprayed on.

Bleeding brakes, right rear still has air, ford 350 2001


You need to bleed the Rear wheel ABS unit first. It is mid vehicle, driver's side frame rail I believe. Until it is bled, you won't get fluid to the rear wheels.

Put in brake fluid but cannot tell if there is a leak or not


After you put the fluid in the brakes start your blazer keep it in park or in nutral with the parking brake on and then push as hard as you can on the brake peddle using the steering wheel as leverage.This should pop any brake line that is leaking a little bit but not enough to pop any good lines.If the peddle slowly goes to the floor check undernieth the vehicle for any signs of leaking.If no signs of leaking look under the hood where the brake master cylinder is and check for any leaking around the mounting surface.If no leaks there check inside the vehicle where the brake peddle goes threw to the master cylinder for leaks on the inside,this does happen from time to time.

How to change the automatic transmission oil and filter. On 4 cylinder engine


Check fluid level every 12 months or 7500 miles, whichever comes first. Transmission fluid and filter should be changed every 100,000 miles. On THM 250C transmissions, intermediate (front) band requires adjustment every 60,000 miles, or as required.
1. With vehicle on level surface, apply parking brake and let engine run at curb idle. Move selector lever through all ranges, ending in "PARK". Remove dipstick and wipe clean, reinstall, then remove again and check fluid level mark on dipstick. Fluid level should check between "ADD 1 PT." and "FULL HOT" marks on dipstick.
RECOMMENDED FLUID Use only Dexron II or equivalent automatic transmission fluid.
CAUTION: If vehicle has been operated for an extended period of time at high speed, or in city traffic in hot weather, or if vehicle has been pulling a trailer, an accurate fluid level cannot be determined until fluid has cooled down (approximately 30 minutes after vehicle has been parked).
So let's get started... 1. With vehicle raised and drain pan placed under transmission, remove front and side transmission oil pan bolts. Loosen rear pan bolts approximately 4 turns each.
2. Carefully pry pan loose with screwdriver, allowing fluid to drain. Remove remaining bolts and oil pan with gasket. Remove screen/filter-to-valve body bolts and remove screen/filter with gasket.
3. Thoroughly clean pan and screen with solvent and dry with compressed air. Paper type filters should be replaced. Install new gasket or "O" rings, lubricated with clean oil, into screen/filter assembly.
4. Install screen/filter assembly to transmission. Use new pan gasket and install pan. Add proper amount of fluid to transmission through filler tube.
5. Start engine with shift selector lever in "PARK" position and with parking brake set. Check fluid level and add as required. CAUTION: DO NOT overfill.

Best of luck :)

Abs and park brake lights come on together


There is an ABS sensor on each wheel. Check each one and make sure they are plugged in first. If they all are plugged in, then you may need to replace one or more of them. You can usually see if they are bad. Hope this helps.
