No, probably not. Engine oil stop-leak would be more likely to help, however that is a temporary fix and I would not recommend it. Just replace the seal.
it is usually the rear brake cylinder that's leaking and needs to be replace on that side.
You might be out of brake fluid. Our rear wheel cylinder was leaking and ran ours out of fluid and the light came on.
chances are its a leaking brake booster or rear seal on master cyl.
IF you have rear wheel drive it may be a grease seal for the rear differential. Otherwise it is probably a wheel cylinder. Check your brake fluid level. GEt this fixed ASAP- Safety concern. Wheel cylinder, brake fluid.. If it's a rear wheel drive vehicle, it may be the axle seal leaking as well. Hello... hello...
Rear main engine seal or front transmission seals
if it is brake fluid your brake cylinder is bad if it is gear oil you have a bad axel seal
change the wheel cylinders or the brake lines
Probably brake fluid, your caliper seal may have gone bad
I found out it`s the cylinder
It is not the brakes leaking oil , Its the axel seals leaking rear end gear oil. If its not gear oil , Then its brake fluid and that means wheel cylinders are leaking.
your wheel cylinder is leaking,you will need to buy a rebuilt or new whl cylinder also new brake shoes and a can of brake cleaner.
Leaking brake cylinder (or caliper piston if it has rear disc brakes). Also if its a rear wheel drive vehicle it could be differential oil leaking from the outer axle seal. If its a brake fluid loss you can monitor the fluid level in the master cylinder .
