Bleeding brakes - \'94 Passat 1.8 petrol - catcher
I\'ve just replaced the brake fluid on my car using a Gunsons easibleed kit. The difficulty I had was getting the fluid to flow at a reasonable rate from the rear brakes. Afterwards I thought it might be something to do with the compensating valve. As the rear of the car was jacked up, the valve would presumably restrict the flow to the rear (as if the car was lightly loaded). The wheels really need to be removed to get at the bleed nipple so I presume the technique should be to lower the rear of the car so the drums are resting on blocks of wood so the valve works as though the car is loaded and allows more fluid through. Has anyone had a similar experience - does my theory make sense?

Thanks

Not an expert but certainly the wheels need to be on the road for the compensating valve to work and some cars need to have weight put in the back to properly adjust the handbrake so you may have a point :)

I've used the same kit and found it tricky to get a good seal on the brake resevoir, thought the cap supplied was cheap and nasty but the whole thing worked ok once secure....but I was in a pit so no need to jack the car or remove a wheel ;)

It might help if you mention the make/model of car, then someone who may have had similar experiences might be able to help you.

Good point Dynamic Dave, I realised I\'d not mentioned the make model. It\'s a \'94 Passat 1.8 petrol.

As far as I am aware. compensating valve has nothing to do with height of car.apportioning valve is there to equalise fluid pressure between rear brakes.and shouldnt affect bleeding.if as you say you have may be to do with bleeder valves?

I've found I can bleed the rear brakes on my 94 Passat with the wheels in place and the car standing on the ground. It is a bit of a contortion though.

What I have discovered is that the bleed nipples are different spanner sizes front and rear!

Cheers, SS
