When antilock brake and brake lights are on and pedal is hard to push and stop.What is typical on a 1990 lincoln mark seven


LEARNING ABOUT THE "TEVES" BRAKE SYSTEM
The hydraulic brake booster on a late model Mark VII and early Continental, is very different from most. It is equipped with something known as a "TEVES" brake system. I'll attempt to teach you what does what and why, so you won't spend a ton of money just because you and maybe your mechanic aren't familiar how it works. The way it's always been is,..."if you don't understand it...replace the whole thing"! The problem with using this technique is, unless you want to spend $2K for the whole thing, your going to be buying a used system....which may not be a whole lot better than the one you have now.
The main parts in the system that we will discuss include an ACCUMULATOR, a HYDRAULIC PUMP, a hydraulic pump RELAY, and a PRESSURE SWITCH. These are the key players in this operation.

THE LOCATION OF THESE PARTS ARE AS FOLLOWS:
HYDRAULIC PUMP MOTOR= Underneath the brake assembly (2 pin connector) Hydraulic pump motor
RELAY = On the drivers side strut tower
PRESSURE SWITCH = 5 pin connector facing the # 7 or 8 spark plug(drivers side)
ACCUMULATOR = Round black ball on the drivers side

WHAT THESE ITEMS DO:
HYDRAULIC PUMP MOTOR is an electric hydraulic pump used to "boost" pressure for the brake assembly. This pump is $900 new!
hydraulic pump motor RELAY is just what its sounds like. It gives the hydraulic pump motor power to come on.
PRESSURE SWITCH is the "brains" in the system. It senses how much pressure is "on line", and when the system needs more pressure, it tells the relay to "power up" the hydraulic pump motor.
Another one of its jobs is to turn on the RED BRAKE LIGHT, then the ANTI-LOCK lights to alert the driver that the pressure is dangerously low. (The reason the anti-lock light comes on, is because the ABS cannot fuction if theres a problem with the manual brakes)
ACCUMULATOR stores energy or pressure like a reservoir. Its there so the hydraulic pump motor only has to come on every 3rd or 5th time. Its design is more complicated, but basicaly the same principle as an air tank on a compressor.

WHAT NORMALLY HAPPENS:
What usually happens is, in time, the accumulator gets weak with age and can't hold the pressure like it was designed too, and therefore, the hydraulic motor comes on every time the brakes are applied....rather than every 3rd or 5th time. This means all these parts are working 3 or 5 times more than they were designed to. This puts an extreme amount of pressure on an already old system.
What we know from this is, the accumulator needs replacing because it's what started all this, but now the pressure switch and relay needs replacement also because it has worked overworked.
NOTE: always replace the relay when replacing the pressure switch. The relay came on every time the pressure switch told it too, so if one is worn out....the others not far behind!

Replaced all 4 dics brakes how do you bleed them


well if you didnt squeeze the calipers in using a tool or c-clamp then there is a bleeder screw on the back of the caliper youll need 2 people for this operation.

1 start car
2 pump brakes till as tight as they will go and hold it to the floor
3 second person undoes the bleeder screw after all fliud or air is gone retightens it(the preson in the car still has brake depressed until vavle is closed)
4 repeat till small amount of pedal travel.

Clutch pedal does not recoil


The clutch master could have leaked its fluild at the slave, line or master itself, Master brake fliud willl be found under the carpet behind the clutch pedel The master is next to the brake master and looks the same only smaller remove the lid add brake fliud and hand pump the clutch pedal. ( Pull up from floor ) this can take alot of pumps. The pressure plate can have gone through and its destroyed the clutch will need replaced and the job should be done by a mechanic that has done the work before this is not a good car to learn the job on as mistakes are very expensive. A good mechanic not learning the job on your car will charge for this work and $800 is likly
