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

As the other readers stated here..... locate the leak, if it's in the line, replace the line. If it's the wheel cylinder, replace the wheel cylinder. Most likely if the wheel cylinder is shot, the line will break trying to get it detached from the wheel cylinder, you'll have to fix the line anyway. Then you have to bleed the brakes all the way around the car.

SOURCE: i have a brake leak beneath the rear right tire...

Depends on where it is leaking. Most cars have a metal line, if this is leaking you can pinch it with pliers or vise grip. Most disc brake system rubber hose, if this is leaking, you are mostly out of luck except to pinch the metal line in which case you now have two parts to be replaced. If it is leaking in brake cylinder itself, again you can only pinch the metal line.

Hydraulic brakes stoped working after blown steering seel? Need help


If there's no pressure on your brake pedal it's due to a failure somewhere in the braking system. I can't see any connection between a steering problem and a braking problem.

Most cars have a split-circuit braking system. That is, the front left wheel is on the same line as the rear right wheel. The front right wheel is on the same line as the rear left wheel.

This is just a safety feature: If one brake line loses pressure, the other line still works and you retain 50% of your braking power.

check the level of your brake fluid. If the level has dropped it indicates a leak somewhere. Though be aware that it is possible NOT to lose brake fluid whilst having soft brakes..

Brake pressure is lost due to either a faulty brake master cylinder or a leak at one of the wheels.

Remove each tyre in turn and inspect the piston on the brake calliper. If there's slight wetness caused by brake fluid that indicates a seal (around the brake piston) has failed and is drawing in air.

There's no need to replace a calliper - overhaul kits are available.

Why rearend leaks by both wheel areas 2003 lesabre?


this is a front wheel drive car there fore there is no rear end like a rear wheel drive. the fluid leak at the wheels is probably brake wheel cylinder/caliper or brake flex hose. check brake fluid level if its down then check for brake fluid leak if not then you will have to check the rear area for some other fluid leak.

I lost nearly all break pressure while driveing my brake and ABS light turned on. So I bleed the brakes and the truck seemed to be working fine then 5 days later i again lost all break pressure with all...


does the truck have rear drum brakes on the rear? if so then the fluid is leaking out of the rear wheel cylinders. or the master cylinder is leaking fluid into the brake booster.

My brakes will not get hard. The pedal goes to the floor. I just changed rear caliper and rotor on the drivers side.


DId you bleed the system after you changed the caliper? If the Master cylinder lost it's fluid while you were changing the caliper, then there is air in the system and you need to bleed the entire system. start with the REAR RIGHT, then the REAR LEFT and then the FRONT RIGHT and last the FRONT LEFT. make sure the master cylinder NEVER runs low on fluid and DO NOT re-use any fluid that you get out of the calipers.

1995 buick lesabre. brakes are gone! fluid leaking from left rear brake.


If they are drum brakes then it is most likely the wheel cylinder. these are not expensive but you will need to replace the rear brake shoes and clean all the parts with brake clean. I recomend replacing the other cylinder while your at it.

If it is leaking from the top area of the plate, and you have drum brakes...then the wheel cylinder is leaking.

Right rear brake has slow brake fluid leak.It's a 99' Ford Taurus


leaking fluid will not cause a brake to lock up unless the wheel cylinder is leaking and caused the brake shoe to swell. If so, you need a new wheel cylinder.
