It sounds like the VE had a lack of confidence at the last moment. the Regulations do make mention to the pipe diameter being reduced by a 1/3, but this is not always possible to see due to corrosion, or as somebody said previously hidden pipes over fuel tanks etc. Any pipes which cannot be seen really a note on a VT32 should be made, and after careful scraping of the effected area a note on your VT40 until the RBT has been concluded, if its not leaked then issue a VT32, sounds reasonable to me.

I spoke to a VE about corroded brake pipes and he said if you were not sure about the level of corrosion stand on the brake pedal during RBT and if it doesn't burst pass it, but in the next breath he said if it was "tree bark" then fail it.
Crikey talk about Grey areas.

Thanks for the reply
I have a couple of really good examples showing why it is important not to carry out a RBT before an underside inspection
Cheers David

I always test the vehicle first for one reason - there may be something become apparent during the test that makes doing a RBT unsafe or not suitable. Piece of metal or sharp object stuck in a tyre that could make a nice mess of your rollers is one example. LSD fitted non-standard - odd car thats been converted to 4wd (sierras common) glad to say few and far between now but things like this or something worse like susspension problems.

The reason I asked was, We had a plastic coated concealed brake pipe on a Renault Megane, Burst while carring out the RBT. it was located above the heat shield for the rear silencer.
I personally throughout a normal working day, due to daily circumstances, carry out the RBT on different vehicles both on the way in or on the way out.
This particular vehicle was RBT on the way in, Highlighting an Issue requiring further investigation during the rest of the normal test procedure.
The "Pipes" are plain Renault green or black in colour, until they dissappear over the heat shield, where they are coated in thicker black plastic.
After applying brake pedal pressure to attain Maximum brake readings, this issue became apparent.
If under normal brake application by Your Presenter whlist normal required checks are inspected, applies the brakes, Then this issue, May Not come to light until the RBT is carried out, Requiring a further visit to the inspection ramp.

| The only difference I can think of, is if you examine the car and then do the RBT last, you can check for any dodgy brake pipes or damaged or under inflated tyres that could cause you grief on the rollers.

You are allowed by VOSA to carry out a RBT on the way in, or on the way out.
What are the advantages and or disadvantages of each option?
