I installed this booster 3 Years ago but the brake pedal still doesn't feel that great. I fitted braided brake lines and adjusted the rear drums as well as fitting dba slotted rotors and quality brake pads. I also upgraded the brake fluid. I have manually bled the brakes various times including the nipple on the brake proportioning set up.
My hilux is a 08 SR and has 265/75 tyres and lifted suspension and is kitted out for touring with steel canopy rooftop tent steel bar work drawers fridge ect so is heavy.
It will eventually chirp a front wheel if I stand on the pedal hard. On down hill sections or when I'm holding on a steep off road section it feels like the brakes will not stop the vehicle.
The pedal is rock hard when the engine is off but when I start it with my foot still on the pedal it will sink all the way to the floor. If I brake and take my foot off and brake again the pedal will go hard and brake performance drops right off. If I stab the pedal coming up to a near stop.it will feel squishy and go at least half way with very poor brake feel. When the engine revs drop you only get one go pretty much, a second go results in the pedal feeling hard.
It feels like maybe the vacum pump cannot keep up?
Anyone else had such dramas?
Cheers
