Clicking/Ticking Noise When Braking To A Stop

MRAGraves · 02-04-13, 06:00 AM

Hey guys,

I've been having an certain issue with my 92 Legend L for awhile now. Somebody else recently started a thread with the same problem but that thread seems dead now (nobody replied after my post). Curious to hear other people's opinion.

My Legend clicks/ticks whenever I'm braking to a stop, happens around 30-40 mph and the noise sounds from the passenger side dash it seems.

It started after I got all four of my 92 Legend's tires replaced at my local Sam's Club. The clicking/ticking noise sounds like it's coming from the passenger side dashboard area (more specifically around the far right air vent?), happens when I brake from a higher speed (30-40 mph). The noise reminds me of a typewriter/tapping noise and it sounds as if something is being scanned or is going through a cycle?

I've been researching what this could be but kept finding myself at threads where people state that when they are driving their Legends they hear a noise when TURNING yet I don't get a noise when I turn or change direction, just when braking. I can say that the noise stopped when the ABS light came on; no more clicking/ticking noise (SN: I pulled codes from my OBD and got ABS problems codes 1-8 and 2-1). After the ABS light came on, I had a previous mechanic change the brake pads and clean the brake calipers to which the ABS light went off but the noise unfortunately came back.

When the problem first started I would get the noise but also the brake pedal would thump under my foot when pressed down. It would be great to find what is the culprit exactly and get it fixed.

Anybody?

I am honestly taking a guess at this one and say it is a faulty ABS pump, it is located near the firewall, on the passenger side, it has another reservoir for brake fluid.

I gravitate towards the explanation given above by Mister, since the ABS pump is located in that area and is a definite noise generator. Recently, I've been noticing a similar typewriter type noise from the passenger front dash side, but only when I drive the car right after starting it. At that time the ABS pumps operates to build-up pressure at the accumulator. Before it was more like a growling sound. I have a 93 Sdn, so 2 out of 5 times I will get a glaring yellow ABS light. And if I don't get the ABS light right after start, good chances I will get it after some brake application. In my case is the solenoids (pump motor over-run).

Now, assuming it is the ABS pump, and that it operates right after you apply brakes at a certain speed, as it tries to build-up pressure, the problem we seem to be having is the type of noise being generated. The ABS pump should generate a rasping sound, not a ticking.

Exactly, like mine for example mine kinda growls between the first few minutes after the car has started, If you have ALL those codes, there is definitely a problem there, that will no longer be a problem with like a Wheel Speed Sensor, more than anything I would lean towards that being your issue, but I suggest getting a pro to this (assuming you wouldn't have the necessary tools) to pull off the proper bleeding procedure.

I've bleed the ABS assembly, cleaned the top portions, and actuated the solenoids several times. That is the only reason my ABS works sometimes. My problem has to be with the solenoids, that is what the Repair Manual says for a Pump Motor Over-run.

Now, the ticking ABS pump noise is a separate issue. The ABS pump should always operate for about 30 seconds after first car movement above 5 or 10 mph. The question is; why recently a ticking noise and not a rasping one? Probably the ABS motor is waiting for its Coroner's Certificate.

yes that is what I want to know, MRAGraves if you find something keep us updated. I just like to know about oddball situations like these.

Could be your timing adjustment box rite in the area you explained but could be wrong its rite behide the egr it only sounds when the rpms are at a certain level but mine didn't matter if I was braking or not

Ok, taking in all the posts. Accumulator is a familiar word as one of the ABS codes I pulled (believe it was the 1-8 code) stated the fix is to replace a part that deals with the accumulator (don't remind word from word). I will talk with my mechanic and try some things out to figure out what exactly could be the culprit. I will deff. be sure to check out the ABS pump and such. Thanks for the guidance.

no problem, good luck on your findings

MRAGraves · 02-09-13, 09:22 AM

I just got my legend back from my mechanic on which other things were worked on. I noticed that I do in fact, when braking to a stop from higher speeds, have not only the ticking noise mentioned before but my brake pedal thumps under my foot; thought that had ceased but it has not. I will keep you all posted with any more updates.

MRA, do you realize when dealing with the Sumitomo ABS system on our Legends one might not really need a mechanic. A better choice might be an exorcists or some reputable shaman.

Said reply was given to me by a Honda certified master mechanic, with a grin in his face.

Whattt, haha, had to chuckle at that one.

I have yet to still get the ABS system checked; I plan to that within the next two weeks. However it seems the ABS works in doing what it's suppose to, it's just activating early. I could be wrong so I will just keep you all updated once properly checked.
