It shouldn't hurt anything to drive it that way. You just don't have any ABS at all as long as that light is on.

I would change both the sensor and the wiring section leading up to it. That is readily available in the aftermarket because the wiring is a known common problem.

This is kinda related , one morning the brake peddle seemed lower than usual , so I did the bleeding process starting with the furthest , bled the master ,replaced the master bench bled it , replaced ABS valve body , bench bled that and the rest of the wheels and master and still low , bought to a garage I trust that activated the ABS for bleeding , he had to clear the ABS code to do it and it's pretty much where it was , it does stop . and I was never really happy with the brake peddle over the years and bleeding didn't bring it up . I think before I posted here about it and it was determined it's just the nature of the beast , even eric at the garage said those years were not a good system , I don'r know ,what do you guys think .?

A frozen slide of a caliper can cause a low pedal with disc brakes.

It would , but the calipers aren't that old and I make sure they can "float" on their pins for even wear , and that's a detail I've noticed some people skip , (they just don't get it ) . I trusted eric to do what he could , I took it to work tonight and did a few panic stops and you wouldn't think about it till you came to a stop and tried to get your foot under the peddle , it's a good car , thanks again

One thing about GM brakes, if you sit still and push on the brake pedal it feels spongy as hell but if you are driving the car, it will stop long before pushing that hard.

Re: 02 buick lesabre ABS codes Sign In

that's how they are , kinda , you can feel, the brakes grab with a little push but they don't stop till you're father down , eric said you can't get the peddle as good as it was from the factory once you replace pads and bleed them and he didn't know why , then I'm thinking about after market proportioning valves but then I won't get
an inspection sticker with the ABS codes , I wouldn't let anyone drive an unsafe car , Stickers ! ? I don't need no stinking stickers ! !

Don't alter it, you'll just open a new can of worms inspection item or not. It is where I am you wouldn't legally be allowed to use that car on a public road. If that isn't at least OK and you know pads and rotors are up to or near spec there's some problem to deal with.
Could it be from when new - yes and complaints ignored. I've driven many only for tests or had just done work and all were acceptable and stopped fine with the exception of ABS suks on glare ice is more dangerous than helpful when all wheels are stationary the vehicle no longer knows one is skidding they all are. That's driver error IMO totally.
I'm not convinced this is right and needs bleeding properly would probably pursue it. The ones that really failed from new were earlier 1990s not into the 2000s models and newer of all I know of and driven myself. Eric may just not have the right stuff to do this for you defaulting on a very old problem with early ones this isn't.
Any which way they must work so you can assertively stop - end of story,

Re: 02 buick lesabre ABS codes Sign In

I'll not argue with that , eric had a couple of ways for bleeding the brakes , the vacuum bottle that works off comp. air and he had an assortment of reservoir caps with a tire stem in the top to use comp air with the bleeder open , he's been at this stuff a while and he lets me use any shop tools I don't have , there's another garage that's more technical I can take it to and pay a little more but as long as it works we're good

Re: 02 buick lesabre ABS codes Sign In

Refresh me please - Do you still have an ABS light on or code?
I'm satisfied with the bleeding now really what can also make a low pedal usually intermittent is the master cylinder. There are two reservoirs in the thing one may be not making pressure till pushrod is down inside it more than it should be. New or used risky at this age for crust inside bore rips seals but you should also have a red warning light - make sure that works.
If real clever bench bleeding a new one you can replace it without re-bleeding the whole system requires some fast work, threaded lines ready and spin freely and push back just a touch from a front and back caliper piston just a tad watch for the tiny bubble at reservoir then watch it also quit.


Try brakes AFTER that and feel the improvement. If any question that failed bleed again. 99% of whacked problems can be just that for what you describe - just that you said you couldn't get other foot under brake pedal when pushing on it isn't usually right - something is wrong and warning you with a light.


IDK - I'm doing mostly my own stuff now and whatever hemorrhaging emergencies come up would do that with the history you have for just this.
If nothing else it would bug me if my own would chase it and fix it no matter what it took LEGALLY is a must. I know more places by area within states are getting sick of the inspection crap many don't prove a vehicle is safe just want bucks. Not looking you up where it's probably registered know GA just cancelled inspections - too much grief was voted on TMK? Can't prove that. Texas it's how far you are from certain major cities or jurisdictions! What a mess with good intentions folks are getting really ticked off for failing over stupid stuff with a perfectly safe vehicle IMO can only be that.


Check the cost of a new master cylinder or another brand if newer it actually should have been done by now. Your call, I personally even if it stopped fine and is all legal wouldn't put up with that complaint on my own and not expect you, family or a customer to either,

Re: 02 buick lesabre ABS codes Sign In

the codes are still up for the pass front sensor and pigtail , HT said I'll still have brakes just not ABS , my panic stops got one tire squealing so I guess one is locking up , eric had to clear them in order to activate the ABS , They come and go , I had a master cylinder from a few years ago that got replaced needlessly , didn't see the line leaking and I put that one in bench bleeding the two of them a couple of times , I left the replacement on the seat but I don't think eric used it or if he bench bled the master he didn't say , , I kept the old lines that I replaced for the fitting end , One thing I learned is use a good tight fitting when bleeding the system as any air could be coming from the sloppy fitting . I don't like having the peddle that low , I've bled the system eight ways from sunday if I get the chance I guess one more time can't hurt . The inspection is good for another 10 months and if NY gets rid of the code requirement for inspections I'd be shocked into a coma , if they have a problem with the low peddle and they can improve it I'd be grateful , I'll replace the sensor and pigtail and get rid of the codes just because , all though some say your better off without the abs , If the wife doesn't ride any ones a** and keeps her head in traffic there shouldn't be a problem .

Re: 02 buick lesabre ABS codes Sign In

Neither of those ways are acceptable ways of bleeding.

if you try to use vacuum, it will simply pull air from the threads of the loosened bleeder and never pull hard enough and even if it did, it is not recommended to bleed by pulling. It will often introduce air through the ABS solenoids.

The other method of using air pressure is just a bad idea for a number of reasons.

The proper way is to pressure bleed using slightly pressurized brake fluid with no air or high pressure which is what a pressure bleeder ball does.

Re: 02 buick lesabre ABS codes Sign In

NY! MA is worse big time for inspections just recently!
Things that can make soft pedal or grab low. Air is #1. Other is a list. Master or rods not correct and are not adjustable. New only allowed in MA no rebults.
Then you aren't as sure how deep the centering hole is - had one wrong too tight, brakes hard and w heat didn't quit braking!
Flex hoses? They are known to block off a wheel but not cause a low pedal. They also can bloat must stay strong. You never let a caliper hang from a hose nor allow them to twist up will fail almost right away.


One brake locks up now? Which one and why just one? Understood rears lose weight as stopping shifts lots more weight to the front rears should lock first and both or something isn't even? Hmmm on that.
Metal lines: They can be pinched, rust out, flares stick to line and twist and more none of those cause soft WORKING brakes you lose pedal almost totally or harder pedal and one wheel doesn't work. Front problem it would pull hard while braking, rears you barely notice if line can't pass fluid properly.
You repeat you DON'T like the feel.
Hey your friend and mechanic Eric may be great and easier for you to deal with. Sometimes it just takes another when something is just not being found and think you should seek another hands on check of this. You can be driving as careful as anyone known and surprises come up there's no room for brakes not to work as intended ever.


Ice/snow or muddy, leaves, hard rain and more driver learns to deal with by the second. All the funky controls just could never cover everything.
Back to the issue. It's not normal if it takes another tech to check and find out why I have to suggest that now,


Tom

Re: 02 buick lesabre ABS codes Sign In

I'll be looking into what HT said , I don't like the vacuum way either for the same reasons air will get past anything loose , I would hope eric used a minimal amount of pressure to do what he did but if it has flaws I'll be going with what HT said , the difference between success and failure is not giving up right ? I don't know which wheel skidded I can only guess , it was only momentary .
