hard brake pedal no breaking (master brake cylinder calipers or lsp valve)? (1 Viewer)

[buschmaster86]

Vehicle is not used for a long time so most probably a frozen cylinder.

The 2 front wheels are not stuck(removed tire and use a vice to push back the brake pad which worded on both sides.

Now before checking all is there a way to know whether its the master cylinder of lsp valve or rear wheel brake cylinders ?

Thanks in advance

Not sure what vehicle you are talking about, but i would start with the master cylinder replacement. You know you are going to have to bleed the brakes anyway after a long park and the master cylinder is up high and can be changed without hurting your back.
