hi how are you guys,

im clueless what is happening to my car, the car now runs shit, the symptoms are

Brake: whilst driving, the brake will be soft, then goes harder, harder till da car is draging and if u stop in traffic its hell as the car doesnt want to move, lifting up the brake pedal sometimes while speeding helps it. the brake fluid also changes its colour to a dirty red from yellow/green.( NEW)

what could it be? master cylinder is stuffed??

the other prob is my car cant seem to pickup any speed its so slow from 1-3000rpms it'll lag at 3000 go to 4000 lag agen.... then its quickly start pulling from 4000rpms onwards , from 1-3 its realli slow and at 4 it feels like YEAAAH HEAPS BETTER... but you can see the rev limiter struggling around 3 alot and car runs like shit..

what could this also be?

any suggestions would be good guys

thanks

p.s i just changed the oil. sparks, and fuel filter thats it <---

The pedal issue is likely due to one of your brake pads dragging and heating/pressurising the fluid until they all start to drag. Thats why it's a prick to pull away.

Just be carefull be cause the fluid will boil eventually and then you will have no brakes all of a sudden.

Jack the car up and rotate each wheel to find which corner the problem is on and go from there.

Fix brakes first as they can kill you, then worry about the missfire.

    • I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!
    • Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.
    • The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!
    • The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
