I ended up ordering discs and pads all round from Lexus,then they asked if I wanted to collect the parts from Toyota(must be the same group)
Now I go straight to Toyota,discs and pads all round came to £357 after discount.The service kit (6l of oil,air filter,pollen filter,oil filter,sump washer)was £51 because they were doing a deal on the oil 5 litres came to 1 pence.
I have nearly got the car up to scratch,I’ve had the wheels refurbed with new Goodyear efficientgrip tyres fitted,new discs and pads fitted(no more grinding)blead the brakes put new fluid in(pedal feels much better)and serviced the engine(can’t see much difference hopefully mpg will be better)
now I need to find where the knocking is coming from on the front suspension and I’ll be happy,although what I’ve spent on it plus the cost of buying it,is probably more than it’s worth.
