There would be break fluid OUTSIDE of the lines and reservoir
It all depends on what part is leaking what fluid. Brake cylinder would leak brake fluid. Axle seal would leak gear oil.
where is it leaking from?
brake fluid leaking from a brake drum indicates the brake slave cylander on that wheel is leaking and needs to be replaced you will not see the actual leak with out removing the brake drum
If you fill your brake fluid up (im assuming you know how to do this) then pump your brakes. Let it set for awhile then check the fluid level, if it is low then check under the car. there would be fluid somewhere down the side of the car where the brake lines run. (on the ground or the actual wires might be wet.) If you are losing fluid but have no leak then it could possibly be leaking into the firewall. case-an-point if your losing fluid you have a leak.
Brake fluid in a Toyota Sequoia could be leaking from several places. Check the wheel cylinders first as they are a common place to leak.
Seal in brake caliper is leaking and needs replacement Flexible brake line to the caliper is leaking and needs replacement
brake pressure loss and pedal going straight to floor is mostly caused by loss of brake fluid or air in brake system look under car and on inside of wheels to see if fluid is leaking. check brake fluid level at master cylander if no fluid seems to be leaking, have the brake system bled for air. this is the simplest remedy to start with if that doesnt fix it have the brake power booster checked to make sure fluis is not leaking into that also check on firewall in engine bay round booster for fluid and on inside of cab on firewall for fluid
Replace the leaking part
take it to the shop to get fixed!
