I want to find red hoses for the radiator for bill blass 1990 mark vii


The only thing I have ever seen are metal hoses. They have a rubber sleeve that hose clamps on.
Earl's has some but I think they are stainless with colored ends.
You can try Summitracing.com or Americanstreetrod.com
May also search for these in Spectra brand.
The only time I have seen colored rubber hoses are blue ones and they are really silicon high pressure hoses (police cars use them)
Good luck on finding red hoses. I like red!

1988 Lincoln Mark VII, Bill Blass, My abs system has seemed to stop working, doesnt want to allow the breaks to stay pumped up... when car is running brakes are gone completely... ive replaced the rotors,...


I have not heard of an ABS causing these problems. Usually, a loss of pressure is a hole in a brakeline or a bad master cylinder.

The first brakelines to leak on my 1988 Bill Blass where those going under the engine. Check in the frame where the lines are routed from the ABS to the front brakes.

I use a Vacuum Handpump Bleeder. As long as there is fluid in the Master, you should eliminate the air. If you have a leak when you draw down each wheel you may hear a whistling, deflating ballonlike sound of the air draw. My handpump has a gauge which will show a pressure drop.

Or you can go the other direction and disconnect the ABS lines to the wheels. When you draw the vacuum from the closed Calipers, there should be little air in the lines. However, a hole in the line will continue to drop the draw from that particular wheel Caliper. This would prove you have an opening in the line.

I replaced the brake master cylinder on my 91 Lincoln Mark 7 with a non high pressure master cylinder and the rear brakes do not hold. Do I need to change the cal. on the rear also?


ANTI-LOCK BRAKE SYSTEM (and HCU-Hydraulic Control Unit)
General Information The 4-Wheel Anti-lock Brake System (ABS) is an electronically operated, all wheel brake control system. Major components include the power brake booster, master cylinder, the wheel speed sensors, and the Hydraulic Control Unit (HCU) which contains the control module, a relay, and the pressure control valves. The system is designed to ****** wheel lockup during periods of high wheel slip when braking. Retarding wheel lockup is accomplished by modulating fluid pressure to the wheel brake units. When the control module detects a variation in voltage across the wheel speed sensors, the ABS is activated. The control module opens and closes various valves located inside the HCU. These valves, called dump and isolation valves, modulate the hydraulic pressure to the wheels by applying and venting the pressure to the brake fluid circuits. Some models are equipped with a Traction Assist (TA) system. The TA system senses wheel spin upon acceleration, turns on the Hydraulic Control Unit (HCU) pump and applies fluid pressure to the appropriate rear wheel. Two additional isolation valves in the HCU will also close to permit fluid to flow only to the rear wheels. The TA system monitors TA usage to avoid overheating the rear brakes. If the system does sense brake overheating, the ABS module will inhibit TA operation until the rear brakes are permitted to cool down.

SYSTEM COMPONENTS The anti-lock brake system consists of the following components:
  • Vacuum booster and master cylinder assembly
  • Hydraulic Control Unit (HCU)
  • ABS module
  • Wheel sensors
  • Pedal travel switch

On 1992-1994 and 1995-00 a scanner is used to perform the brake bleed. But on yours, I think it's different according to the manual.

What do you mean change the cal. on the rear also? Do you mean Caliper?

Power brake booster compatibility - 86 crown vic to 83 town car


i think if there is a problem it would be if one had A.B.S. and the other did not, otherwise i can't see any problem. just have to look at it and see if everything lines up. i believe the boosters are the same, if they look the same and bolt up the same i don't see any problem. you might want to chk. with a ford dealer just to see if there is a differance in volume on booster.
