Grand Ams don't use a proportioning valve. The rear brake lines should split above the rear trailing axle and go to each wheel. They have rubber flex lines that attach to the metal brake lines, but I'm not sure what valve you are talking about, or exactly where.

Where is the location of brealine proportioning valve 96 linclon towncar


I am not familiar with the car. Brake proportioning valve is usually positioned these days above or near the rear suspension.

Brake proportioning can be by g-valve, pressure limiting valve or most often these days by a load sensing limiting valve. The latter is connected to the rear suspension by a spring and/or an adjustable link. In some cases there are two valves; one each side for independent rear suspension.
The checking and adjustment of the linkage is generally part of the routine maintenance and is often maladjusted by ill-informed but well-meaning people.

I have seen the g-valve fitted on the front bulkhead by some manufacturers. In theory this type can be fitted almost anywhere.

That would likely be caused by the ABS brake hydraulic control unit leaking pressure to the rear brake caliper, not the proporting valve..

Hi. My Toyota Camry 1995 was failed in Rear Breaks test on breaks' capacity measuring machine by NZ Vehicle Testing despite replacing Break Drums and Break Pads with new ones. The cuase is adhered to...


The prop/valve is located near the rear of the car and is inbetween the front brakes and the rear brakes.It's job is to adjust the braking force between the front and rear wheels.If only one person is in the car,you get more braking force at the front wheels.If you have 4 people in the car and the boot is full of luggage,you will get more brake force directed to the rear brakes.What it prevents is the car from spinning out from a rear wheel lockup.
It will be located by looking at the rear suspension.A smallish metal rod will connect the suspension to the chassis of the car and it will be hooked up with the brake lines.As weight is loaded to the rear suspension,the rod will slightly move a small lever on the prop/valve.This is where you will see the adjustment.
Hope this helps you

Villager GE 95 liquid escape in a brake system


It is a brake load sensoing valve that applies more pressure to the rear brakes as you load the vehicle. It is $375 from tascafordparts.com. Get one from the junk yard or just bypass it.

usually just the lines are leaking and can be replaced.
Valve, Brake Load Sensor Proportioning The Villager has a brake load sensor proportioning valve (2B547) that is mounted on the vehicle frame and connected to the rear axle housing (4010) . When the vehicle is unloaded, the brake load sensor proportioning valve closes and partially reduces hydraulic pressure to the rear wheel cylinders (2261) . As the vehicle is loaded, the weight presses down the back end of the vehicle on the rear springs (5560) . This activates the brake load sensor proportioning valve which opens and supplies more hydraulic pressure to the rear wheel cylinders . When the vehicle is fully loaded, the brake load sensor proportioning valve is fully open and provides full hydraulic pressure to the rear wheel cylinders .

check at the proportioning valve--some have a pin that sticks out from the side, when bleeding the brakes try to push that pin back in. But first check to see why this happened--fluid leak to rear wheels, brake hoses cracked and air getting into the system??????
