New Brakes

[Cant Get Right]

Gonna change my brakes, As everyone knows the 2.4 brakes are rubbish, So can i fit bigger brakes and if so what will they come off, would it be maybe the 3l or maybe even a Land Cruiser????

Bigger brakes will require bigger wheels.
Braided hoses will give a firmer feel to the pedal, plus brand new brake fluid will make a difference too.

Got bigger wheels, 16", came off a landruiser

Might look into braided hoses and replacing fluid, seems a no bad option from what ive read, just thought bigger brakes would be less wear and tear too, would be easier to do hoses and just fit new pads and disks

Been suffering from this for some time... until now...

what can you do...

firstly, the brakes on the 2.4 and the 3l late 2nd gen are big enough... the trick is getting the braking pressure into them... so this all boils down to detail...

braided hoses... making sure the vacuum assist is upto scratch... new worn in pads... making sure all the seals in the calipers and drums are good... and adjusted correctly... give the hand brake a lot of focus too... make sure the lpsv valve is set correctly... especially if you have lifted the truck...

and...

change your master cylinder for something a little bigger...

In the US they tend to go for the 80 series master cylinder, but with out a lot of modification on a right hand drive truck the brake lines run too near to the heatshield and turbo, and you don't want heat near your brake fluid if you can help it.

Next best option is a 3rd gen master cylinder. The bore is larger than the 2nd gen, but smaller than an 80 series... and its a direct replacment. Now that my new pads are definitely run in and the caliper is replaced that muppet MOT blew out (sure he was trying to break my truck)... My truck being overweight... but it really stops now...

I suppose the tyres will also help considerably... and the right tyres in the appropriate conditions would also have 'impact'... pardon the pun.

And keep the fluid refreshed, as it tends to absorb moisture as time goes by... that will also help...

Cheers for that guys, will start with sorting the hand brake, new pads disks, braided hoses and fresh fluid.
Thanks

Don't do it, you know you're a tw4t and break things! I don't want you messing around with your brakes and killing yourself mate...

As for brakes! A general rule (A VERY GENERAL RULE!), to get more pressure onto the pads/shoes, you need a master cylinder with a bigger bore or cylinders/calipers with a smaller bore. This will give you more pressure at the pads/shoes for the same effort on the brake pedal.

Think of the master cylinder as a wummin and the brake pistons as her shoes. A fat burd in stillettos will give you more pressure at her heels than a skinny burd in cubans would!

I take it you have moved the Load sensing valve after I did the lift. Or were you not listening by that point.

[Albannach]

I take it you moved the Load sensing valve as instructed, after I did the lift. Or were you not listening by that point.

That implies that he was listening at some point?

Brian stop being a tube, u never told me to move the sensor. Just like u never adjusted my steering thingy , and never adjusted my fuel filler pipe.

Na al try it maself first. but no need to try put me down bud especially when i dont know feck all about trucks, and u know that

Don't feck about with your brakes if you don't know what you're doing!

[Cant Get Right]

Yes good point Andy, taken on board. they will be done under supervision. misses, mums boyfriend is a mechanic. dont wanna be asking Bri all the time

I think you mean the other way round. If you use a larger master cylinder and smaller wheel cylinders you will get much less pressure at the wheel cylinder, the other way round ie, smaller master cylinder OR larger wheel cylinders will give greater pressure at the wheels but less travel.
Look at it as a gear ratio for if both cylinders are the same dia ie 20mm the pressure in psi. on the master will be the same as the pressure in psi. on the wheel cylinder.
If you 1/2 the area by reducing the dia on the master and keep the wheel cylinder the same you will get double pressure in psi. on the wheel cylinder.
If you increase the dia on the master to twice the area of the wheel cylinder you will get only 1/2 of the pressure at the wheel cylinder.

If it were me I would possibly change the servo unit to a larger diameter servo unit but keep the hydraulic master piston the same as it is, or put in a brake hydraulic pressure intensifier after the servo unit.
I used to run this system in my race cars with 100% success.

Hope this helps
