Does anyone know if there is a suitable brand new donor brake booster that would fit a mk 3 mr 2?
We all know that parts are slowly but surely becoming scarcer and Toyota no longer make boosters for our toys.
The booster is holding the brakes on when the peddle is pressed ( I have to lift the pedal with my foot) so it is clear that the vacuum is not restoring on the pedal side of the booster when the brake pedal is released. The return spring on the pedal is in good condition.
Ive confirmed all calipers are fine. I removed the vacuum hose and plugged it to ensure smooth running. I then took the car out and all brakes released perfectly. Sure the brake effort required was more but the car still stops on its nose.

J-Spec will no doubt have one, or Josh at Midlands & East coast.
It is still listed in Japan but it's $560 !
Ive considered both of them, great service from jspec on my subframe.
Just dont fancy putting a second hand booster in. Especially off a scrapper.
Do it right once ( i hope)
I would be happy with any parts from j-spec. In past 2.5 years I have had many parts including engine, rear bumper, engine cover (both in mint condition ready to bolt on), suspension, brake calliper, headlights, various trim & electrical parts all in perfect condition.
Just ask them for one from a low mileage car.
From jspec...we can supply a good used one for £39 plus post
They are good. Messaged this morning, replied this morning.
Just waiting for the invoice
Fitted the part from jspec this morning.
Getting the old booster out was super easy. The hydraulic lines to the abs module did not even have to be removed as there is a loop in both lines that allows movement of the servo.
Just above the pedal is a pin with a clip, there is a spring on the pin as well, easy to remove.
The booster studs are anchored onto the booster and pass through the bulkhead AND the pedal frame arrangement.
The pedal frame arrangement is under tension. Sooo before you pull the booster off the bulkhead jam something tightly below the lowest part of the pedal framing. Otherwise it slips down and you need two people to align the booster bolts to the bulkhead and pedal frame arrangement.
I discovered this the hard way and spent an hour and a half cursing and raising my blood pressure.
Then its an easy job (NOT) contorting yourself to fit the four nuts onto the booster studs hust behind the pedal framing.
Pin clip and spring fit easily, dont forget to tighten the servo onto the booster.
Taking the car down my drive which is about three cars length I just about put myself through the windscreen.
Damn these brakes are good
good job, well done!
Some time ago I asked a question about the longevity of the booster.
This post is the first I am aware of on this topic and although of only academic interest to me now I do like the hint about "jamming something", that is the sort of tip that is soooo helpful to those that follow on.
Good job x2
@Mr 2 macleanWith reference to "contortion " accessing" the pedal cluster , in retrospect would it have been helpful to remove the driver seat?
Iirc I did that when I replaced the bulkhead gasket on the steering column.
Something else that doesn't get a lot of mention on here but mine was in a sorry state on my 2002 car.
When did we start calling a brake servo a booster anyway ??
