Rep Power: 0

Hi Guys

I got Honda EK3 which is built in 1998 and model is Exi. No ABS and Air bags

Few weeks back i noticed that Breaks are not suffecent. when i apply breaks i feel that front right side get locked and front lest is not that much. so i finally replace the both caliper pistons and did fully repair.

this got slightly improvment bit not 100%

this car got Master pump with primary and secondary pressure pipes that will go to brake proportioning valve (6 line – 2 in and 4 out)

When we apply breaks i think this valve give a pressure to, Front right side and rear left side via Maser pump Primary line.

Next

While the peddle de-press the master cylinder secondary line go to proportioning valve and give the pressure to front left and rear right wheels

(Please correct me if this wrong)

My Problem is

1. how can i test the proportioning valve if there is a block or malfunction
2. How can i test master cylinder secondary line.

can somebody help me to rectify this issue please

if you guys got EK3 98. (no ABS) can you apply break at 40 Km and tell me how you feel it, (please be careful)
.
Thanks all
