Question about 1988 Toyota Pickup
Brake and charge warning lights stay lit
Brake light warning indicates possible low brake fluid in the reservoir;
Charge warning light indicates battery not charging which can be caused by defective alternator/regulator, slipping belt, corroded fusible link from alternator to battery B+ terminal.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FixYa.

OK, first of all, replacing brake pads has absolutely NOTHING to to with your antilock brake system OR your traction control system.
You will have to scan your Antilock Brake System (ABS) module to find out what the actual problem is that is causing the lights to come on.
With all of that being said, the MOST LIKELY cause of your problem is either a faulty wheel speed sensor or a problem with the wiring harness going to the wheel speed sensor.
GM has had problems with BOTH on seveal of their models. If the sensor has a problem, the entire wheel bearing and hub assembly must be replaced because the sensor is serviced ONLY in a complete assembly. However, proper diagnosis should be performed - EVEN if you find a fault code that says "wheel speed sensor". I have seen many mechanics replace the bearing and hub assembly only to find out that the problem was actually being caused by the harness (EXPENSIVE MISDIAGNOSIS).
Both parts are sold at AutoZone and other parts retailers. (see pictures below)
There are also many other things that can possibly cause the symptoms you are describing - this is just the most common cause. Again, PROPER DIAGNOSIS needs to be performed.

Have you finally sorted your problems. I think it might be a faulty alternator on its way out.
Could you please be kind to let me know. I have the same problem and just need to be sure of what to do.
