Hi I recently rebuilt my brake system bleeding from a dry setup followed the workshop manual instructions the left caliper has acceptable brake pressure but on the right caliper I can't even get any fluid to it under pressure the pedal is rock hard , I removed the line from the master cylinder and pumped got not the best result can this unit be rebuilt its on a 2wd sapphire cosworth

 

The rear line is shared between both so of its got pressure on one side it should be the Same on the other

You've been using the ignition to build up the pressure correct?

 

Srry for got to mention it was the front

 

Fronts share the same line too

 

If what you are saying is correct why does the abs block have 3 holes

 

One for the front
One for the back
One for the return

 

The front brake links are separate and there's no such thing as a return.

 

I think the abs block does have a return to the master cylinder, it is the larger centre outlet on the master on a 4x4 and car.

 

we are basing our assumptions on the later abs setups, which have a separate master cylinder setup and a separate abs valve block

in which the master has one feed to the block for the rear line, one feed to the block for the front line and another return back from the block

the block then has 2 inputs and 4 outputs, one return to master, one line to the rear and one for each front

one the early versions the block was integrated into the master assembly

if you have the later one then you should be seeing pressure from the master to the block and it will be the output that is the problem, sometimes these have been caused by something as simple as an air lock

 

I guess that is where the confusion comes from. On the LHD cars the master cylinders and valve blocks are always integrated. So I was only talking about the lines towards the calipers.
