(brakes) ( tech) (80)



Hi guys
I know I have a few little issues to work out with the cruiser and when it
stops raining I may have a look etc. But I have to move on to my next idea,
I have ordered my 33 inch tyres and 16 inch rims from the UK and should have
them next week I hope. When theey arrive I plan to get my OME springs and
struts fitted and then put the new wheels on. Thats that so now I would like
to know about inproving the braking power of my cruiser. My cruiser is the
early 92 (FEB) so I know that they (TOY) changed or upgraded after this
period. I know not to get the drilled rotors because of the chance of stuff
getting stuck in the holes, and that the slotted rotors may be better. I do
not have access to a later model in a breakers to get the larger
calipers/rotors etc so do any of you have an idea of how I can improve the
braking. I did tyr to get the 100 series pads put into the calipers but was
told they did not fit. Correct me if im wrong but the calipers determine the
size of the pads that can be fitted and the rotors determine the size of the
pads YES. So if I want to improve the braking do I have to get bigger
calipers or is there a cheaper way. Will the 100 series calipers fit the 80
or am I barking up the wrong tree again. Thanks for any ideas you have.

Hi John,
For the time being I would just stick to the stock brakes with Toyota
There are some 3rd party pads called Axxis Ultimate Brake pads made of
kevlar and ceramic made by Bendix-Mintex in Australia that make a pretty
big difference, however I have failed to find a UK supplier, so you may
end up having to buy from the US.
Firstly, if you are likely to have problems with cross drilled rotors,
the chances are you will get similar problems with slotted ones (crap
building up in the slots).
Don't forget the disks are vented and these vents can easily fill up
with crud as well, particularly the backs that pick up all the spray
from the fronts - you should always try to spray them out when you
finished a days sever mud plugging. (After getting bogged on Salisbury
plain last year the vents on by back brakes were absolutely caked in mud
and took a lot of cleaning.
The only company that makes good quality replacement disks for 80s is
DBA in Aus and I know there are plenty of people on the lists in Aus and
the US that use them without problems when severe off roading.
The LC brakes changed in July/August '92 and I guess the 100 series pads
will only fit calipers after that date.
As for fitting the later disks and calipers to you model, I believe that
this is possible - Dana on the 80s list has done this on his '91, but I
don't know if it was a straight swap of the calipers, disks and wheels
or more work was involved.

Thanks for all that Julian, I think as usual ill get digging to see what I
can get. So if the rotors are drilled and slotted they are better than the
stock but just need cleaning after a fun day off road, so if on road thay
will be a lot better and not need cleaning am I correct. If I need or want
new rotors, the slotted and drilled ones with the ceramic pads would make a
good difference YES. I find it amazing that after I get one thing done to
the cruiser I want another one done , might check me self into somewhere
with big walls for addiction issues. But then they would all check out and
id be left alone. I am psoting you the mag today sorry for the delay.

Hi John,
The whole things with brakes is cooling - the brakes use friction to convert
the rotational energy of the wheels/tyres/vehicles into heat.
The quicker you can dissipate the heat and the higher the temperature the pads
can deal with more efficient the braking.
The vents on the disks are there to improve cooling - cross drilling them
improves this cooling further.
The slots on the high performance disks generate more friction and thus
improve the braking. They also help prevent the pads from glazing, which
reduces their friction.
Obviously high performance pads containing Kevlar and Ceramic material can
withstand much higher temperatures and therefore are less likely to fade.
A typical example of fade problems is when you are going down a logs steep
twisty hill and are driving on the brakes - the further you down the hill the
hotter they get and thus the less efficient they are which can lead to them
not working at all.
My old SAAB 9000 turbo had pretty poor pads on the front, late one night
whilst racing through Milton Keynes trying to get home, the brakes got so hot
and didn't have time to cool between roundabouts that by the time I got to
about the 5th I had no brakes at all - it made it a lot more interesting!

Ah Julian your mad or was that when you were young, fearless and brave
because you were invinsible like all the young drivers think they are with
there speedy fart cars. Just the thoughts of trying to keep the cruiser on
the road with no brakes gives me the shivers big time. I really cant stand
the way it wallows at bends and feels like it needs more road and the way
you can not take your rye off the road for a few seconds only to discover
you have travelled either to the right or left of where you thought you
were. I never had this with any cars I had , makes looking at things not
directly in front not advisable. No brakes and roundabouts to go around and
not over.

Hi John,
Only a couple of years ago - I may now be 40, but still consider myself
to be young, fearless, brave and foolish!
I have always been a fast driver - I think I need to get another rally
car to satisfy that side of my character.

Hey Julian Thanks for that, it was even clear to me wow I hear you say but I
did shake the head and loosen the two brain cells and of course the holiday
helped, but for how long I hear you ask. Now all I have to do is find the
bleed valves and away I go of course when it stops raining again.

Hey Mik
Go on out of that my med works fineeeeeeeeeeeeeee opps, your starting to
slag a bit like an Irish man no insult intended at all better be carefull
there I dont want any competition in that field you may just out class me
in this aswell as you do in the cruiser side of things. How are you enjoying
the Irish summer I was thinking of trading in the cruiser to buy a boat to
go to town any ideas on this. Thanks for the usual down to earth advice
asusual its always welcome. Watch you dont get too much sunburn out ther in
