I have a Prado 90 series TD Auto. time for a service so took it in to mechanic today. one of the the items on the list is the brake pedal seems to be a little bit sticky - after braking the pedal does not push back but releases a little slowly. just noticeable but is there and I do not want it to get any worse.
Mechanic said - "that can be nasty" - ususally means master cylinder problems and these are a non serviceable item, new ones costing about $5,000!!!
Anyone else had experience with this in a landcruiser, prado or hilux? If so what was the outcome?
Cheers

I wanted to put new rubbers, etc into my Jack master cylinder just as routine maintenance, and found out that can't be done - as with yours, it's a replace entire master cylinder job.
I was too scared to find out the price, but $5000 seems a bit excessive even for Toyota??
Years ago I used to get master cylinders sleeved with a tube of stainless steel, and put new rubbers in - the end result was better than original, usually.
I haven't investigated that option yet, as there is no brake problem, but surely it can be done? The non-serviceable item would be the outer casing which would be able to be sleeved.
The Jack one is a standard 1" twin piston job - what's the bet a unit from any vehicle could be fitted as long as its twin piston 1" ?

I had that done in
Bamaga on a 99 Jack (master and slave cylinders) using original parts and it was about $600 including the air freight. Way less than $5,000.

Not sure on the cost, but the cause is usually DOT4 Brake Fluid being used, and it can stuff up the Toyota seals. Toyota specify DOT 3 and the only place you can buy DOT 3 these days is the Toyota dealer.

thanks Phil
I was aware of that and the mechanic is too - he told me when I got some brake fluid take on a trip as spare. Just hope his staff know the same.

PBR also make a Dot 3 fluid. It is in a yellow container and you can buy it in either 500ml or 4 litre containers. I get
mine in 4 litre containers from Repco.
90% of cars with ABS use Dot 3 fluid.
Dot 4 swells the seals and yes the Toyota Prado and 100 series master cylinders are expensive as they incorporate the ABS unit.
I would do a full brake fluid flush with Dot 3. Grab the Toyota brand as its reasonably priced and see how you go.
