One of the cars we use without ABS will not lock the rears unless I pull on the hand brake, another car locks the rears after some effort and a third car will lock all four wheels almost simultaneously.
Suspension can help or hinder depending on how old and type, whether it is standard with a lot of km or brand new and set up for the car. Also tyres can have a huge effect. How old are the tyres, what pressures are you running and what is the general condition of the tyres?
But with your dramas, I would be looking at the brakes. As had been said before, when you replaced the pads did you also replace the grease on the slider pins? What condition were the pins in when you did the swap? What did the piston seals look like on the calipers? What was the general condition of the callipers?
What does the pedal feel like? When you lock the fronts first how are you using the brakes? Are you smashing the pedal as hard as you can under heavy braking?
And for bleeding from the furthest point first, it is to maximise the amount of air you get out of the braking system. Sometimes you may need to bleed the brakes a few times doing it by pumping the pedal. If you have the time, gravity is best, or if you have the pressure bleeder that is better again if used correctly.
Im running about 34 psi and i've got 2 year old re002's with plenty of meat left 60+ %
When i did the brake pads i made sure to grease the sliders as i no there prone to seizing. Assuming the pins are seized the brakes would stick when i let off the pedal wouldn't they?
Ive got fairly new coilovers in the car, wether they are setup to maximise braking is another story but i don't think there hindering braking anymore then the 20 year old originals
Pedal feels good when i brake not too spongey, no play, and not a lot of travel is needed to get them to bite
when i lock up i slowly apply and build up pressure up to about maybe a bit more then half the pedal travel and then the fronts will lock simultaneously or sometimes the drivers side front depending on conditions.
Can the handbrake adjustment effect rear bias? I find my handbrake isin't very good, at least 8 clicks until its full tight and will do anything on a hill. Then when i take my rear wheels off the rear wheels drag a decent amount. Say if im rolling at 5kph on flat ground and i rip the handbrake it will take a few seconds to stop.
Cheers
