Hi! My name is ***** ***** I can assist you with this. I may need some additional information from you first in order to give a complete answer.
I don't do brake questions, but we have several techs here on site that do. I will opt out of this and allow one of them to provide an answer. Not sure when that might be as they come and go all during the day.
Hi John, My name is***** will be glad to try to help. I recommend flushing the system further and bleeding the system thoroughly. If a new switch did not correct the light it means that there is air in the system still or you are losing brake pressure for some reason. Bleed the system further until you can get the system to pressurize enough to turn the light off. If this does not resolve you either have a leak in the system, air in the system or a faulty master cylinder. Let me know
Yes there will be a brake pressure switch and if there is air in the system the pressure switch will trip. Try jumping the pressure switch for test purposes to confirm its the switch triggering your light to see if it goes off and on when connection and disconnecting the jumper. If that is the case it means electrically its working but you have low pressure in the system.... This can be airbound from the flush and possibly only require more thorough bleeding.
on a two wire switch you use a jumper wire to connect the two terminals. Connecting and disconnecting acts as a switch to open and close the connection .
you will be jumping one terminal over to the other terminal. The switch just makes that connection.
Thanks for the update. So you are getting a small amount of air instead of straight fluid? That is enough to throw a light.
Yes. Bleed starting at the furthest away from the master cylinder to the closest. Two people. One pumping the pedal then holding, the other then opening the bleeder until the pedal goes to the floor, close the bleeder and then lift the foot from the pedal and go again keeping an eye on the fluid level until there is no air. If the switch and wiring are good and this does not get the air out try having them pressure bled at a shop. Now this is for a brake system fault light. If the service brakes are okay and it is the park brake indicator staying on let me know. That will be a problem i the park brake circuit.
Hi John, Did you get this resolved? If so please take a moment to rate my service as that is how the site credits my time for helping on the site.
Thanks for the update. Let me know
Hi John, Just checking in so your question does not get lost in the archives. How are things going?
Thanks for the update. I understand. We have a lot of ice and snow where I am and freezing temperatures. Unfortunately for me I have to go out in it if there is a call. Keep me posted.
