90coupe

Thanks, I will probably get to it over the weekend depending on the weather, had to convert the garage to a bedroom and bath for my folks due to my dad having altzheimers, and new garage wont be startesd til they can dig for foundation. I will keep posting all my results and once again Thank You

OK...Pulled the car out of thee this morning and drove it home, only the ABS light on and the brake fluid as you guys expected is overfull approx 1/4 to 3/8 in over the full line. I ran the tests as requested but ran them 3 times and the results follow: Test 1 - ABS light on constantly Red light took 9 pumps to go off each time tested. Test 2 - 25, 24, 25 pumps per test Test 3 - red light out in 28 seconds each test yellow remains on constant Test 4 - 40 seconds, 42 seconds, 40 seconds Test 5 - 3 pumps each time tested Test 6 - Hard to tell as was overfull but distance was no more than 1/2 inch each time and no noticable loss of fluid Test 7 - Tap felt and thump heard each time. So now all looks like it is in the normal range, Red light goes out, but Yellow ABS light is on constant. BTW, braking seems just fine both around town and hiway driving while returning from the dealer.

Sure sounds like the service manager had, to be nice about it, not told me the truth, if the accumulator has nothing to do with the pressure, it was either 2600 all the while or 1200 all the while, not one then the other ... I am pulling the car out tomorrow and will test myself and post results ... thank you all for your help past and present and future with this problem

The only thing i am allowing this guy to do is the brake test tomorrow. At this point i believe that they have no experience as suggested and i want a real mechanic , not a guessing parts changer, which i will start my search for immediately, will post the brake test results when i get them and thanks again

Thanks for the welcome, and the area, geographicly has been added as suggested. As for the Brake test, already printed and dropped off to the dealer and told him i am expecting it in full completed by end of day tomorrow. Also not to "try" changing any parts until i get it and get back to him. Thanks all for your continued help. This car sure aint my old 55 chevy. Oh and yes the pump stops just before it hits 2600 psi according to the guage.

After talking to the service manager, the system went from a max of 1200 psi with the old accumulator, to 2600 psi max with the new, no leaks at the pressure switch, but "seeping" from the main valve unit or block, also according to him, the pump is fine but both lights red and abs are still on and ofcourse he cant get ahold of that main valve unit/block. From what i have read on here via those a lot more knowledgable than me, it sounds liek the pressure switch is bad possibly in addition to the piece holding the main valve he talks about, it also sounds like the pressure switch is a common failure and would not be bad to have a spare around, are they available?

Added as requested to signature line, forgive me i am new to this

Reatta is a 1990, ie: 90 reatta brake leak in the subject..lol as for the test, it is hard to do now that the dealer has it and the thing is according to him now leaking, if the accumulator was bad as i understand is common, woould changing it out cause for a higher pressure in the pump and consequently for the pump to leak ?

Dealer replaced the accumulator and now says the "control unit", i am assuming the pump, is leaking. havent seen this on the forum, but i am new, both ABS and red lights were on when i brought it in, but no leaks and i had brakes.. Any ideas or is this dealer just a guessing parts changer. Dennis

Hi all, I have a 90 coupe that i just bought and the dash is blank except for the word "error", two large zeros "00" and a light that says "electrical problem". The car runs fine but i have no guages nor a speedo. turning of and on does nothing, but the test button displays the entire dash. As i am new to these cars, does anyone have an idea of what the problem could be ? Thankyou in advance for any help. Dennis... dennisddryburgh@verizon.net
