Hello, I have a 99 jeep Cherokee and the brake light came on. Went to auto zone and filled up the brake fluid reservoir and I had to add about 8-10 ounces of brake fluid. Is that a normal amount of fluid to loose from pad wear over time? It has been about 25K miles since I replaced the rear drums and 15k miles since I replaced the front pads. I have not lost any fluid since and I have driven it for a few hours.
Did you bleed the brakes the last time you did the brake job? Yes, the level gets lower as the pads wear. From what I'm understanding, you probably already had a low brake fluid level after resetting your calipers, and then a few thousand miles later with the pads getting worn the level got lower and triggered the brake light. To be sure, inspect all your brake lines and master cylinder while someone is pumping the brakes. And make sure all your bleeder screws are closed fully.
no you should not have to add brake fluid at all.
The level goes down as the pads wear, but you DO NOT top it up. If you do, then it will overflow when you change the pads. The fluid should only fluctuate between the top and bottom level indicators.
The fact that the light came on could mean two things:
1. the fluid wasn't at FULL when the pads were last changed.
2. you are leaking brake fluid. <--- this is bad
Agree with the others. Probably wasn't full to start.
Maybe put a piece of tape at the level it's at now, and then check it for a couple weeks.
No noticeable change and you're okay.
I did not bleed the brakes during my last brake job, but I did not change the calipers. I believe it may have just been low after my last brake job. Been driving it for the last few days, haven't seen any leaks and it is still full.
