ABS system and break bleeding
ABS system and brake bleeding
If we want to bleed the ABS module we need a dealer who can do it. What we need is a smart guy who can solve the problem.
Surely to make the solenoids in the ABS work we just need to apply some electrical pulse to them? Take of the plug and apply the current to the correct terminals Would that work?
Most say bleed the longest brake line first, is that really true any more? Each of the four lines originate at the ABS pump there is no tee in the front or rear systems like the old days, each brake has its own circuit.
Changing the master cylinder carries the risk of getting air into the ABS pump.
Ideas?

You need to see ‘bi-directional’ in the specs, also some work only on some models as I have found out. One of my readers says it does it but it does not. I complained to the maker and got no answer.

I guess it is where you come from. My Canadian English spell checker corrects the word spelled to spelt. We developed the language and you guys just messed it up.
Looking at what passes on this forum as English I do not do too bad, I do not use spelling based on the sound of the local accent.
spelled in the past tense and as a past participle. In all other main varieties of English, spelt and spelled both work as the past tense and past participle of spell, at least where spell means to form words letter by letter or (with out) to make clear. Outside the U.S., the two forms are interchangeable in these uses, and both are common.
No comments on the post except digs. What about some sensible remarks.

Spelled vs. spelt

No, still watching to see if anyone has an answer to this ABS bleeding other than wet grass, and who knows, maybe that IS the answer.
Re: ABS system and break bleeding
The grass method may work but some air may just go back to where it came from.

Wow
180, you’re constantly providing assistance. Everyday you point a forum members to correct threads and provide backup docs and links for most topics.
You (180) ask for assistance, in that ask you inadvertently spell a word, correctly, one that sounds the same but has a different meaning (I believe it’s called a homonym) and you’re called out for an error. It’s a forum about cars, I think we all know the intent break vs brake. Let’s rise above being petty.
ladies and gentlemen in the country South of ours, we try to do things differently in Canada, Like take the high road.
Here are a few more for you. English in its original form. I know it will blow your minds
labour
neighbour
cheque
There is enough pettiness out there, we’re a group with a common interest. Let’s stick to our common obsession and not look for ways to pounce on one another.
180, as a fellow Canuck and from all Canucks on the forum we stand on guard for thee
🇨🇦
You rock

I was NOT being petty, I was merely adding a check mark to my side of the ledger
Re: ABS system and break bleeding
That is what I understand, bleed first then slide around the local soccer pitch. Race home to avoid the police and bleed again. Repeat as necessary until the brakes are nice and firm or the cops catch you.
Re: ABS system and break bleeding
Can always go back to using mechanical brakes. As salesmen of behind-the-times-cars said in the 1920s, "Do you really trust a LIQUID to do your braking?"
Heck, on a 1973 MG Midget I owned the master-cylinder was not yet divided internally into two sections. I had to replace it once and when it gave out you really noticed!

Re: ABS system and break bleeding
This is a question for the electronic geniuses we have on the forum.
When the ABS is used what kind of signal does the unit get from the sensors? I was thinking of buying a spare ABS unit and seeing if I could trigger it to actuate the solenoids inside it so they pumped out the air in the ABS unit on the car. The connector to the ABS unit has a lot of pins on it and finding the correct pins may be a bit of a headache.
Obviously, the idea is to replicate the dealers DRBIII units function to bleed the ABS module.
Can it be done?
