Break line leaking to the rear left wheel - 1993 Toyota Corolla

remove and replace the wheel cylinders on both rear wheels as it is generally not a good idea to try and reclaim them. (If one is leaking then the other one will be seeping as well). As there will be oil on the linings it is necessary to replace them as well or you will have grabbing brakes/ no brakes and side skids in heavy braking

was the wheel cyl leaking? make sure there are no other leaks anywhere i see rusted out line on these a lot check down left side of undercarage fuel lines and brake lines run along there .if you have abs you should only have to bleed rears the front are on different valves no air can get in from a rear leak.If no leaks anywhere master cyl most likely

Follow the brake line starting at the left rear wheel, there is no diagram for brake lines, take the tire off and inspect (look) left rear wheel, It will be wet where the leak is, if the inside of the tire is wet then you might want to check the brake cylinder, behind the brake drum. You might want to take it to a shop and get it fixed, It is your life and others, if you can't stop.

you have a leaking brake line and/or fitting. metal lines rust and break over time.

Most likely rellted to the rear wheel cylinder. You need to remove the tire, probably replace the brake shoes if they are wet with fluid, wipe down brake drum with carb or brake cleaner, install new wheel cylinder and put everything else back together. Wheel cylinder is available through most auto parts outlets. Probaby less than $15.

From your discription, if it is square in shape and has 3 brake lines attached to it, it is the rear brake junction block. Double check and make sure it isn't a brake line that is attached to it. If the leak is above the rear axle on back of the wheel, that's the rear wheel brake cylinder.

You will need two people, one to pump the pedal and one to open bleeders at the wheels. Start at the right rear wheel open bleeder and have someone press the brake pedal down and hold it (do not release pedal until bleeder is closed), close the bleeder and repeat until no air is coming out. Proceed to right rear wheel repeat above prceedure, proceed to right front wheel repeat above, go to left front wheel repeat above, and then check pedal for proper feel if it is a solid pedal with no fade then you have finished. If you have a low pedal or fade then bleed master cylinder. You can bleed master by breaking loose the rear line (do not loosen line all the way) just enough that fluid comes out when pedal is pressed and held. Have some press the pedal while line is loose and hold it, tighten line and repeat until no air comes out, repeat same proceedure with the front line. If you still have a low pedal or fade then you may have a leak somewhere or a faulty master cylinder.

to do a complete job. you need to bleed all 4 wheels, starting from Right Rear. Right front. Left Rear. Left Front.

Sounds like you have a leak in the brake system. The fluid you are seeing is brake fluid.

You need to get this fixed asap.

Air in the lines, or a leakey line or caliper, do you see any fluid leaking on the rims? or under the car? if not they prolly just need to be bled.
