flushed brakes, now ticking at idle from rear

[fenixus]

hello,

it's not a problem or any sort of major issue.
just curious what it might be. after my 2000 solara i4 had a brake flush a funny ticking sound started coming from the rear of car - it's neither of sides, i believe i can hear it most in the middle.
it's a faint sound, can hear hear it only at idle in parking lot in fairly quiet areas (especially at night).

i flushed brakes with a vacuum pump and Valvoline DOT3&4 less than a month ago, all went well, however rear brakes had lost of air (especially passenger side) in them. i bled them in this order: RP, RD, FP, FD.

am i missing something? like another bleeding valve in the middle or some magic trick i was supposed to do while bleeding brakes (regular DIY, nothing crazy).

i thought the sound maybe goes away after a while ... well it didn't.

it's just a sminor annoyance, but am very curious...

I am guessing it is not brake related at all, exhaust heat shield?

[JohnGD]

Yeah, if it's not moving it's not the brakes. +1 exhaust.

[ekopel]

can you be more specific on the ticking noise?

[fenixus]

hmmm. exhaust you say? actually it would make more sense (i have ABS by the way). will have to check the pipe to tell more.

will try to describe the sound tomorrow evening. sorry, solara is not my daily driver . need to listen to it again, as i forgot what it was alike.

you know that's funny. once i started talking about it out loud, the sound disappeared making me look like a lunatic
however i heard a single click coming from rear driver drum (e-brake applied) whenever i was pressing on brake pedal.

might also need to check the rear drums for sticking/clicking brakes. but that will have to wait. i will try adjusting rear drums with a star screw or what was its name.

also i noticed the e-brake is catching higher than in past, might need to adjust that too. currently even at 8 clicks on handbrake, car pulls forward.

do i have maybe a proportioning valve somewhere? someone asked if car has ABS, yes it does as far as i know.

as per noise description... well i haven't heard it for a few days, but as far as i remember it was similar rather to steady metallic clicking (pace almost same as engine idle, maybe even slower).
i think that might be exhaust related as you pointed out.
it seems i could hear it much better before resetting ECU due to spark plugs & wires swap from Bosch to NGK and cleaning the TB about 2 weeks ago. might be that ECU finally got properly adjusted only after swap to plugs/wires it likes LOL

tell me if what i say is completely upside down, wrong or nonsense (non-mechanical, learning dude here).

"also i noticed the e-brake is catching higher than in past, might need to adjust that too. currently even at 8 clicks on handbrake, car pulls forward."

Sounds like you need to adjust the rear brake shoes a bit tighter (closer to the drums). There should be a bit of drag when you spin the drum.

"it seems i could hear it much better before resetting ECU due to spark plugs & wires swap from Bosch to NGK and cleaning the TB about 2 weeks ago"

None of these services would require resetting the ECU.

thanks Mike. this weekend I will adjust the rear brakes first to see if it helps.

the reason I reset ECU was to make it adapt faster to new/different plugs, wires and higher fuel grade. wasn't sure if it was necessary, but since my car was running not right with Bosch parts, I just reset it. the reason was even better because I had to disconnect battery anyways for terminal cleaning and re-seating the battery properly on a tray (clamping arm was holding it down improperly).
