Lotsa braking problems after a major service

Sounds like the electric brake pump isn't working. Is there a fuse for that? Possible the accumulator lost its charge?

 

There are alot of threads search "hard brake pedal" in 328 section also 348 we have the TevesII system you can google that also to see other cars that had same system and issues.

overfilling the reservoir will not give you an issue

however it may not have been overfilled and its internally dumping into the reservoir from the accumulator

try the tests here: (dont pay attention to the buick!)

I recall reading something about the ABS systems having additional steps for the bleeding process, especially the t.

 

Before doing something wrong, I would consider to bring the car back to S. Power..or that they pick it up at your home.
It cannot be, after a major, you have those issues without consulting them first.

You made his day! hope it will be something simple though..!

 

My hunch is they did not bleed the system correctly after the major. Not a big deal. If they did then the Master cyl is sending Fluid back into the resv. This is a classic sign of failed internal seals in the multi chamber master cyl. Take a look at the fluid flow on one. What a PITA. Good news is parts are all off the shelf stuff. PM if you need anything and I can give you the cheats.

Just a hunch, but when I had my 3.2 mondial (non abs) I would often find that upon start up the brake pedal would not move. It was so hard but after a few pumps up and down it would go to normal pedal feel. It ended up being the non return valve from the engine that creates the vacuum for the brake system to work. It's such a cheap part. The original is metal and fits between 2 hoses. They are no longer made in metal and are now plastic and is the same part as used in the 430.
Like I said it's just a hunch but was my cheapest fix for under $10.

 

Peter,

ABS does not have the valve, its uses a motor to create pressure

 

So the valve is valid on non abs as in the mondial.
I wonder what the function of that part is for on the 430 then as what's what they use?

 

Totally different ABS system.

 

connectors and Mondials and you have more then one connector bad connectors are generally an issue in old(er) cars. Good to hear it was something minor!

 

It helps putting their name on a forum like this.....

CLEAN CLEAN CLEAN your connectors!

 

Meant to post a new thread....

 

I have often wondered where the vacuum is tapped. Where is this $10 weak item? As for anti-lock they are a very mixed blessing. Mostly because they greatly increase stopping distance on hard packed snow or ice. Something like 25%. Car and Driver did a test decades ago. But I knew it the first time I used my first anti-locks on a downhill ice sheet. NO brakes.

The reason for this is that locked-up brakes scrape a wedge of shavings in front of the tire which really helps. Anti-locks do not have that capability. I no longer live with such matters. However, when I lived in ChicagoLand I even disconnected anti-locks on certain days.

 

PS: I have two cars without anti-lock and three with anti-lock. The insurance companies at first offered a 15% discount for anti-locks. They have not done that for a very very long time. And then there is the rediculous assertion you can steer if you have anti-locks. On ice you can not steer whatever you are driving. And since I am a 'G' force sort of guy I practice max brakes almost every time I drive.

My speculation is this: The average driver has never activated anti-lock which means he is in a panic stop the first time. As much as I have practiced braking there is no practical way to practice steering during an anti-lock panic stop. You would need a specialized course or an airport runway. I believe everyone should fully activate their anti-lock brakes at least once a week.

Today, for instance, I did max brakes on the Mondi at least half a dozen times. They are not anti-lock and are a bit touchy. But after hundreds of practice stops I am getting better at it. And I will argue it is better for the brakes. Why? First, if you stop from 60mph in two seconds as I do or four seconds the brakes are used to transfer about the same amount of energy. If you do it in two seconds the brake calipers are well exercised over many fewer revolutions. Tires I can afford.
