When I push in on the brake padle it activate the brakes but when I lift my foot and try to brake again the paddle seems to harden untill theres no brakes.Brake-paddle remains hard for a couple of seconds but when you release the paddle and drive for a metre the brake seem to work again.It seems as if theres a leak on the brake air line because when I remove the air hose at the brake booster it **** very poor.Please assist.

Re-calibrate your brake calipers by lifting your caliper housing and using a c clamp to push the caliper back into the housing. DO NOT TAKE THE CAP OFF OF THE BRAKE FLUID RESIVOIR AS THIS COULD LET MORE AIR INTO THE LINES. After you have reset the calipers, try resetting your brakes as before; pump brake pedal until it gives good resistance. With your foot still depressing the brake pedal, start the vehicle. If it does it again, then you may need to re-check where you bled your lines for integrity.

Hope this helps.

If you don't have a handle above the brake to pull, it most likely is the type that you step on again to release. Step and press on it firmly - all the way down - and let up slowly. You should feel up pushing back on your foot as you lift it up.

yes there is. its the brake pedal switch, if it is bad or out of adjustment car will not start. you have to put foot on pedal to activate switch to start car. it is on top backside of brake pedal arm.

The rear brakes on the Spectra will always engage less than the front brakes. If you have to push hard on the brake pedal then you probably have air in the brake lines from the last brake pad replacement. The brakes need to be bled with this method: Use 1/8 inch 2 foot long hose from parts store and attach from bleeder valve ball on the brake caliper to a bottle partially filled with brake fluid. End of hose should be submerged in bottle. With second person holding brake pedal to floor, slowly turn bleeder valve counter clockwise (loosen tiny bit) with wrench and watch for dirty brake fluid to create bubbles in the bottle. When bubbles start, quickly tighten bleeder valve back to tight. Second person lifts foot while valve is tight and then pushes pedal to floor again and THEN you again open bleeder valve slowly turning counter clockwise and watch for bubbles. Repeat until no more bubbles can be created in the bottle where the hose is submerged. Move to next caliper and repeat. For a firm brake pedal you will need to repeat this on all four calipers. My 2003 Kia's rear brake pads "fell apart" and never wore out in 190000 miles because they do not get used. The braking power is primarily in the front disk brakes on this model. Removing and replacing the rear drum brake linings did not even require me to bleed the brake lines. They weren't that tight before or after the replacement procedure.

If you have a soft brake pedal and have to push hard to slow down or pump the brakes to slow down then you probably have air in the brake lines from the last brake pad replacement. The brakes need to be bled with this method: Use 1/8 inch 2 foot long hose from parts store and attach the hose from bleeder valve ball on the brake caliper to a bottle partially filled with brake fluid. The end of the hose in the bottle must be submerged in the fluid in the bottle. With a second person holding the brake pedal to the floor, slowly turn bleeder valve counter clockwise (loosen tiny bit) with wrench and watch for dirty brake fluid to create bubbles in the bottle. When bubbles start, quickly tighten bleeder valve back to tight. Second person should lift foot, pump and then while valve is still tight should push the pedal to the floor again and THEN you again open bleeder valve slowly turning counter clockwise and watch for bubbles. Repeat until no more bubbles can be created in the bottle where the hose is submerged. Move to next caliper and repeat. For a firm brake pedal you will need to repeat this on all four calipers.

***Seek out professional help this vehicle is not safe to operate.***


Check the vacuum line going to the brake booster.

This is the big round chamber behind the master cylinder.

Hope this tip helps.

Step on brake paddle with engine off, then with foot on brake paddle start engine, brake paddle should go down a few inches, also check for vacum at power brake booster under hood ( sit in back of master cylindre ) if you have vacum there and brake paddle did not go dnow a few inches, replace brake booster.

Brake light switch is active by the brake paddle.

Before you start,take a picture or do a sketch of the spring or linkage around the brake paddle.

Move the seat back will give you better access.

Press the paddle and the inner side (closer to the firewall) of the paddle will activate the switch.

Please keep in mind there are fuse(s) to protect the lighting circuit.

Check all the fuses before you R&R the brake switch,

brake lockup. due to tight torance from the brake padle to the master boot. loosen the nut on push rod behind the brake padle and decrease the rod travel.
as far as the clutch, you may have the same problem.
do a serach in the Internet for the tolerance. usually is 1/8 to 1/4"
