You must find a way to  lure some coupes to a gathering on the sands of 
Sarasota. It's been way too  long and my 560 misses the good fellowship and 
fried shrimp.

Over the years, I have had (and  heard of) some strange faults on these 
wonderful cars. But I can't work this  one out.
Here is what happened.
I was driving into town one night (about  8 miles from home) when it 
started to rain. As you would expect, I turned on  the wipers. They worked for 
about 30 seconds, then "poof" they stopped just as  I was coming up to a red 
light. I hit the brake pedal, and it just sank to the  floor. Luckily, I had 
already slowed down considerably before braking, so with  a few pumps on the 
pedal I managed to stop OK.
To cut a long story short.  Driving very carefully and quite a bit of 
pumping of the brakes, I managed to  get to my destination and was also lucky the 
rain stopped for my return  journey home.
Next day, I checked the fuses, and as expected, the fuse that  powers the 
wipers had gone. I replaced it with a new one, and hey presto, they  worked 
perfectly. (Nothing strange there I hear you say). I then thought, now  to 
get to the brake problem. So jumped in the car and set off to my local  garage 
I use for service and repairs (when I can't be bothered to do it  myself). 
As I came up to the first junction at the end of my road, I hit the  brake 
pedal and nearly went through the windscreen. I then did a few tests up  and 
down my own street and managed to stop on a dime every time. The brakes  
worked perfectly with no sign of the pedal sinking to the floor. So I  
cancelled my visit to my local garage and nearly 3 months later everything is  still 
perfect.
Now I can understand the fuse for the wipers going on a 1991  car, 
especially as I don't use it that much these days, but can anyone explain  to me how 
the hell can replacing the fuse for the wipers fix my brake problem  as 
well at the same time. I just can't work this one out.
If anyone has any  ideas or recommendations, I would love to hear from you.
Yours very  confused,
Vance

There is no co-relation between the two.  Check the vacuum
line  from the 

brake-booster to the intake manifold (lower plenum).   Great big plastic

thingy.  If that is good, put vacuum gauge on  main vacuum line and see if

it holds.  Yours very drunk in  Florida.  If the car was here, I could find
it in

no time flat.  Sayonara.

Hi Attila,

Thanks for the  fast reply and advice. I will check and let you know the 
results (when I get  round to it).
Quite a coincidence, I used to live in Florida, but that was  4 years 
before my 560 was built when I used to drive around in a monster of a  7.5L 
Lincoln Continental which did as much as 8 miles to the gallon. (but who  cared  
back then?).
Great times back then. Makes me wish I was back  there. Have one for me.

Cheers,

Vance.

When the wiper/brake problem happened  did you happen to notice if the ABS 
light came on? My '91 did the same thing  once. I replaced the OVP relay and 
never had the problem again. These cars are  very quirky when there is the 
least bit of voltage problems, either over or  under the optimum. (12.5v at 
the battery with car not running, 13.3 to 13.5v  at the battery with the 
engine running.)

;-) Attila, when're you going to get down  here to Sarasota? The MarVista

You guys are good in solving problems.  Two weeks ago I was doing a Real 
Estate job. I parked the car and get out  taking the key with me.
About 10 minutes later I got in my 87 560 SEC and  want to start the 
engine. But no nothing happened, nada. Totally dead. I took  the key and open the 
drivers door to get out.
The car has an after market  Clifford alarm system that started making 
noise. I pushed the button and the  alarm went off. I did not know why this 
happened and decided to try to start  again. The car started at the turn of the 
key and has done it every day. No  repeat problem. Why?

Hi Jay,

Good point  regarding the OVP relay, but I replaced mine to some years back 
to fix a high  idle problem. Before I replaced it, both the ABS and  the 
ASR lights were  on permanently as well as the high idle, but luckily, no 
signs of any of those  problems since. So to answer your question, no, the ABS 
light wasn't on when I  had the brake problem. But I certainly won't dismiss 
the OVP relay should the  problem happen again. Although I am convinced 
Attila is right, and there is no  link with the fuse (or any electrical 
component) in my case.

One last  silly thought though. Is it possible to accidently disturb a 
brake vacuum line  or another part of the braking system by lifting the hood, 
working in the  engine compartment, then closing the hood again? If so, then 
it could be what  happened to fix my brake problem when I replaced the fuse 
for the wipers if I  accidently and unknowingly knocked or moved a vacuum 
line back into  place.

I know, what a stupid idea I hear you say. But I have learned  not to 
dismiss any idea or suggestion when it comes to these cars.
Thanks  again for your tips.

Vance.

When the wiper/brake problem  happened did you happen to notice if the ABS 
light came on? My '91 did the  same thing once. I replaced the OVP relay and 
never had the problem again.  These cars are very quirky when there is the 
least bit of voltage problems,  either over or under the optimum. (12.5v at 
the battery with car not running,  13.3 to 13.5v at the battery with the 
engine running.)

Subject:  [W126 Coupe] Strange Fault (& fix)

Over the years, I have had (and  heard of) some strange faults on these 
wonderful cars. But I can't work this  one out.
Here is what happened.
I was driving into town one night (about  8 miles from home) when it 
started to rain. As you would expect, I turned on  the wipers. They worked for 
about 30 seconds, then "poof" they stopped just as  I was coming up to a red 
light. I hit the brake pedal, and it just sank to the  floor. Luckily, I had 
already slowed down considerably before braking, so with  a few pumps on the 
pedal I managed to stop OK.
To cut a long story short.  Driving very carefully and quite a bit of 
pumping of the brakes, I managed to  get to my destination and was also lucky the 
rain stopped for my return  journey home.
Next day, I checked the fuses, and as expected, the fuse that  powers the 
wipers had gone. I replaced it with a new one, and hey presto, they  worked 
perfectly. (Nothing strange there I hear you say). I then thought, now  to 
get to the brake problem. So jumped in the car and set off to my local  garage 
I use for service and repairs (when I can't be bothered to do it  myself). 
As I came up to the first junction at the end of my road, I hit the  brake 
pedal and nearly went through the windscreen. I then did a few tests up  and 
down my own street and managed to stop on a dime every time. The brakes  
worked perfectly with no sign of the pedal sinking to the floor. So I  
cancelled my visit to my local garage and nearly 3 months later everything is  still 
perfect.
Now I can understand the fuse for the wipers going on a 1991  car, 
especially as I don't use it that much these days, but can anyone explain  to me how 
the hell can replacing the fuse for the wipers fix my brake problem  as 
well at the same time. I just can't work this one out.
If anyone has any  ideas or recommendations, I would love to hear from you.
Yours very  confused,
Vance

Hi Attila,

Thanks for the fast reply and advice.  I will check and let you know the 
results (when I get round to it).
Quite a  coincidence, I used to live in Florida, but that was 4 years 
before my 560 was  built when I used to drive around in a monster of a 7.5L 
Lincoln Continental  which did as much as 8 miles to the gallon. (but who cared  
back  then?).
Great times back then. Makes me wish I was back there. Have one for  me.

Cheers,

Vance.

Ronny,

I also have  an after market alarm and immobilizer fitted. A few times in 
the past, I have  had exactly the same symptoms as you describe (as far as 
the starting is  concerned). To correct it, I needed to disconnect the battery 
for a few  minutes, then reconnect again. This has reset the 
immobilizer/alarm system  enabling the car to start first turn of the key.
Maybe when you pressed the  button to silence the alarm, maybe it managed 
to reset the system and  therefore having the same  effect.

Regards,

Vance.

You guys are good in solving problems. Two weeks  ago I was doing a Real 
Estate job. I parked the car and get out taking the key  with me.
About 10 minutes later I got in my 87 560 SEC and want to start  the 
engine. But no nothing happened, nada. Totally dead. I took the key and  open the 
drivers door to get out.
The car has an after market Clifford  alarm system that started making 
noise. I pushed the button and the alarm went  off. I did not know why this 
happened and decided to try to start again. The  car started at the turn of the 
key and has done it every day. No repeat  problem. Why?

My vacuum line going from the back of  the intake manifold melted against 
the EGR manifold.  Nice melted shape,  eh?

Luckily a 5-minute job to cut a new one and carefully route it down  the 
firewall & away from the EGR & transverse pipes...

Oh yeah  and put the smog pump belt back on after yesterday's alternator 
belt  mishap.

Cheers,
Gerry
